  • v0.9.3.a Changes

    August 09, 1999
    • Install libRSAglue.a when OpenSSL is built with RSAref.

    Ralf S. Engelschall

    • A few more #ifndef NO_FP_API / #endif pairs for consistency.

    Andrija Antonijevic [email protected]

    • Fix -startdate and -enddate (which was missing) arguments to 'ca' program.

    Steve Henson

    • New function DSA_dup_DH, which duplicates DSA parameters/keys as DH parameters/keys (q is lost during that conversion, but the resulting DH parameters contain its length).

    For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is much faster than DH_generate_parameters (which creates parameters where p = 2*q + 1), and also the smaller q makes DH computations much more efficient (160-bit exponentiation instead of 1024-bit exponentiation); so this provides a convenient way to support DHE ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of utter importance to use SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); or SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); when such DH parameters are used, because otherwise small subgroup attacks may become possible!

    Bodo Moeller

    • Avoid memory leak in i2d_DHparams.

    Bodo Moeller

    • Allow the -k option to be used more than once in the enc program: this allows the same encrypted message to be read by multiple recipients.

    Steve Henson

    • New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts an ASN1_OBJECT to a text string. If the "no_name" parameter is set then it will always use the numerical form of the OID, even if it has a short or long name.

    Steve Henson

    • Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp method only got called if p,q,dmp1,dmq1,iqmp components were present, otherwise bn_mod_exp was called. In the case of hardware keys for example no private key components need be present and it might store extra data in the RSA structure, which cannot be accessed from bn_mod_exp. By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key operations.

    Steve Henson

    • Added support for SPARC Linux.

    Andy Polyakov

    • pem_password_cb function type incompatibly changed from typedef int pem_password_cb(char *buf, int size, int rwflag); to ....(char *buf, int size, int rwflag, void *userdata); so that applications can pass data to their callbacks: The PEM[_ASN1]_{read,write}... functions and macros now take an additional void * argument, which is just handed through whenever the password callback is called.

    Damien Miller [email protected]; tiny changes by Bodo Moeller

    New function SSL_CTX_set_default_passwd_cb_userdata.

    Compatibility note: As many C implementations push function arguments onto the stack in reverse order, the new library version is likely to interoperate with programs that have been compiled with the old pem_password_cb definition (PEM_whatever takes some data that happens to be on the stack as its last argument, and the callback just ignores this garbage); but there is no guarantee whatsoever that this will work.

    • The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused problems not only on Windows, but also on some Unix platforms. To avoid problematic command lines, these definitions are now in an auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).

    Bodo Moeller

    • MIPS III/IV assembler module is reimplemented.

    Andy Polyakov

    • More DES library cleanups: remove references to srand/rand and delete an unused file.

    Ulf Möller

    • Add support for the free Netwide assembler (NASM) under Win32, since not many people have MASM (ml) and it can be hard to obtain. This is currently experimental but it seems to work OK and pass all the tests. Check out INSTALL.W32 for info.

    Steve Henson

    • Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections without temporary keys kept an extra copy of the server key, and connections with temporary keys did not free everything in case of an error.

    Bodo Moeller

    • New function RSA_check_key and new openssl rsa option -check for verifying the consistency of RSA keys.

    Ulf Moeller, Bodo Moeller

    • Various changes to make Win32 compile work:
      1. Casts to avoid "loss of data" warnings in p5_crpt2.c
      2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned comparison" warnings.
      3. Add sk_<TYPE>_sort to DEF file generator and do make update.

    Steve Henson

    • Add a debugging option to PKCS#5 v2 key generation function: when you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and derived keys are printed to stderr.

    Steve Henson

    • Copy the flags in ASN1_STRING_dup().

    Roman E. Pavlov [email protected]

    • The x509 application mishandled signing requests containing DSA keys when the signing key was also DSA and the parameters didn't match.

    It was supposed to omit the parameters when they matched the signing key: the verifying software was then supposed to automatically use the CA's parameters if they were absent from the end user certificate.

    Omitting parameters is no longer recommended. The test was also the wrong way round! This was probably due to unusual behaviour in EVP_cmp_parameters() which returns 1 if the parameters match. This meant that parameters were omitted when they didn't match and the certificate was useless. Certificates signed with 'ca' didn't have this bug.

    Steve Henson, reported by Doug Erickson [email protected]

    • Memory leak checking (-DCRYPTO_MDEBUG) had some problems. The interface is as follows: Applications can use CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); "off" is now the default. The library internally uses CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() to disable memory-checking temporarily.

    Some inconsistent states that previously were possible (and were even the default) are now avoided.

    -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time with each memory chunk allocated; this is occasionally more helpful than just having a counter.

    -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.

    -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future extensions.

    Bodo Moeller

    • Introduce "mode" for SSL structures (with defaults in SSL_CTX), which largely parallels "options", but is for changing API behaviour, whereas "options" are about protocol behaviour. Initial "mode" flags are:

    SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when a single record has been written. SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write retries use the same buffer location. (But all of the contents must be copied!)

    Bodo Moeller

    • Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options worked.

    • Fix problems with no-hmac etc.

    Ulf Möller, pointed out by Brian Wellington [email protected]

    • New functions RSA_get_default_method(), RSA_set_method() and RSA_get_method(). These allows replacement of RSA_METHODs without having to mess around with the internals of an RSA structure.

    Steve Henson

    • Fix memory leaks in DSA_do_sign and DSA_is_prime. Also really enable memory leak checks in openssl.c and in some test programs.

    Chad C. Mulligan, Bodo Moeller

    • Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess up the length of negative integers. This has now been simplified to just store the length when it is first determined and use it later, rather than trying to keep track of where data is copied and updating it to point to the end. Steve Henson, reported by Brien Wheeler [email protected]

    • Add a new function PKCS7_signatureVerify. This allows the verification of a PKCS#7 signature but with the signing certificate passed to the function itself. This contrasts with PKCS7_dataVerify which assumes the certificate is present in the PKCS#7 structure. This isn't always the case: certificates can be omitted from a PKCS#7 structure and be distributed by "out of band" means (such as a certificate database).

    Steve Henson

    • Complete the PEM_* macros with DECLARE_PEM versions to replace the function prototypes in pem.h, also change util/mkdef.pl to add the necessary function names.

    Steve Henson

    • mk1mf.pl (used by Windows builds) did not properly read the options set by Configure in the top level Makefile, and Configure was not even able to write more than one option correctly. Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.

    Bodo Moeller

    • New functions CONF_load_bio() and CONF_load_fp() to allow a config file to be loaded from a BIO or FILE pointer. The BIO version will for example allow memory BIOs to contain config info.

    Steve Henson

    • New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. Whoever hopes to achieve shared-library compatibility across versions must use this, not the compile-time macro. (Exercise 0.9.4: Which is the minimum library version required by such programs?) Note: All this applies only to multi-threaded programs, others don't need locks.

    Bodo Moeller

    • Add missing case to s3_clnt.c state machine -- one of the new SSL tests through a BIO pair triggered the default case, i.e. SSLerr(...,SSL_R_UNKNOWN_STATE).

    Bodo Moeller

    • New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications can use the SSL library even if none of the specific BIOs is appropriate.

    Bodo Moeller

    • Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value for the encoded length.

    Jeon KyoungHo [email protected]

    • Add initial documentation of the X509V3 functions.

    Steve Henson

    • Add a new pair of functions PEM_write_PKCS8PrivateKey() and PEM_write_bio_PKCS8PrivateKey() that are equivalent to PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more secure PKCS#8 private key format with a high iteration count.

    Steve Henson

    • Fix determination of Perl interpreter: A perl or perl5 directory in $PATH was also accepted as the interpreter.

    Ralf S. Engelschall

    • Fix demos/sign/sign.c: well there wasn't anything strictly speaking wrong with it but it was very old and did things like calling PEM_ASN1_read() directly and used MD5 for the hash not to mention some unusual formatting.

    Steve Henson

    • Fix demos/selfsign.c: it used obsolete and deleted functions, changed to use the new extension code.

    Steve Henson

    • Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c with macros. This should make it easier to change their form, add extra arguments etc. Fix a few PEM prototypes which didn't have cipher as a constant.

    Steve Henson

    • Add to configuration table a new entry that can specify an alternative name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, according to Mark Crispin [email protected].

    Bodo Moeller

    • DES CBC did not update the IV. Weird.

    Ben Laurie lse des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. Changing the behaviour of the former might break existing programs -- where IV updating is needed, des_ncbc_encrypt can be used. ndif

    • When bntest is run from "make test" it drives bc to check its calculations, as well as internally checking them. If an internal check fails, it needs to cause bc to give a non-zero result or make test carries on without noticing the failure. Fixed.

    Ben Laurie

    • DES library cleanups.

    Ulf Möller

    • Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit ciphers. NOTE: although the key derivation function has been verified against some published test vectors it has not been extensively tested yet. Added a -v2 "cipher" option to pkcs8 application to allow the use of v2.0.

    Steve Henson

    • Instead of "mkdir -p", which is not fully portable, use new Perl script "util/mkdir-p.pl".

    Bodo Moeller

    • Rewrite the way password based encryption (PBE) is handled. It used to assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms but doesn't apply to PKCS#5 v2.0 where it can be something else. Now the 'parameter' field of the AlgorithmIdentifier is passed to the underlying key generation function so it must do its own ASN1 parsing. This has also changed the EVP_PBE_CipherInit() function which now has a 'parameter' argument instead of literal salt and iteration count values and the function EVP_PBE_ALGOR_CipherInit() has been deleted.

    Steve Henson

    • Support for PKCS#5 v1.5 compatible password based encryption algorithms and PKCS#8 functionality. New 'pkcs8' application linked to openssl. Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE KEY" because this clashed with PKCS#8 unencrypted string. Since this value was just used as a "magic string" and not used directly its value doesn't matter.

    Steve Henson

    • Introduce some semblance of const correctness to BN. Shame C doesn't support mutable.

    Ben Laurie

    • "linux-sparc64" configuration (ultrapenguin).

    Ray Miller [email protected] "linux-sparc" configuration.

    Christian Forster [email protected]

    • config now generates no-xxx options for missing ciphers.

    Ulf Möller

    • Support the EBCDIC character set (work in progress). File ebcdic.c not yet included because it has a different license.

    Martin Kraemer [email protected]

    • Support BS2000/OSD-POSIX.

    Martin Kraemer [email protected]

    • Make callbacks for key generation use void * instead of char *.

    Ben Laurie

    • Make S/MIME samples compile (not yet tested).

    Ben Laurie

    • Additional typesafe stacks.

    Ben Laurie

    • New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).

    Bodo Moeller

  • v0.9.2.b Changes

    May 24, 1999
    • Bignum library bug fix. IRIX 6 passes "make test" now! This also avoids the problems with SC4.2 and unpatched SC5.

    Andy Polyakov [email protected]

    • New functions sk_num, sk_value and sk_set to replace the previous macros. These are required because of the typesafe stack would otherwise break existing code. If old code used a structure member which used to be STACK and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with sk_num or sk_value it would produce an error because the num, data members are not present in STACK_OF. Now it just produces a warning. sk_set replaces the old method of assigning a value to sk_value (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code that does this will no longer work (and should use sk_set instead) but this could be regarded as a "questionable" behaviour anyway.

    Steve Henson

    • Fix most of the other PKCS#7 bugs. The "experimental" code can now correctly handle encrypted S/MIME data.

    Steve Henson

    • Change type of various DES function arguments from des_cblock (which means, in function argument declarations, pointer to char) to des_cblock * (meaning pointer to array with 8 char elements), which allows the compiler to do more typechecking; it was like that back in SSLeay, but with lots of ugly casts.

    Introduce new type const_des_cblock.

    Bodo Moeller

    • Reorganise the PKCS#7 library and get rid of some of the more obvious problems: find RecipientInfo structure that matches recipient certificate and initialise the ASN1 structures properly based on passed cipher.

    Steve Henson

    • Belatedly make the BN tests actually check the results.

    Ben Laurie

    • Fix the encoding and decoding of negative ASN1 INTEGERS and conversion to and from BNs: it was completely broken. New compilation option NEG_PUBKEY_BUG to allow for some broken certificates that encode public key elements as negative integers.

    Steve Henson

    • Reorganize and speed up MD5.

    Andy Polyakov [email protected]

    • VMS support.

    Richard Levitte [email protected]tte.org

    • New option -out to asn1parse to allow the parsed structure to be output to a file. This is most useful when combined with the -strparse option to examine the output of things like OCTET STRINGS.

    Steve Henson

    • Make SSL library a little more fool-proof by not requiring any longer that SSL_set_{accept,connect}_state be called before SSL_{accept,connect} may be used (SSL_set_..._state is omitted in many applications because usually everything appeared to work as intended anyway -- now it really works as intended).

    Bodo Moeller

    • Move openssl.cnf out of lib/.

    Ulf Möller

    • Fix various things to let OpenSSL even pass "egcc -pipe -O2 -Wall -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline" with EGCS 1.1.2+

    Ralf S. Engelschall

    • Various fixes to the EVP and PKCS#7 code. It may now be able to handle PKCS#7 enveloped data properly.

    Sebastian Akerman [email protected], modified by Steve

    • Create a duplicate of the SSL_CTX's CERT in SSL_new instead of copying pointers. The cert_st handling is changed by this in various ways (and thus what used to be known as ctx->default_cert is now called ctx->cert, since we don't resort to s->ctx->[default_]cert any longer when s->cert does not give us what we need). ssl_cert_instantiate becomes obsolete by this change. As soon as we've got the new code right (possibly it already is?), we have solved a couple of bugs of the earlier code where s->cert was used as if it could not have been shared with other SSL structures.

    Note that using the SSL API in certain dirty ways now will result in different behaviour than observed with earlier library versions: Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) does not influence s as it used to.

    In order to clean up things more thoroughly, inside SSL_SESSION we don't use CERT any longer, but a new structure SESS_CERT that holds per-session data (if available); currently, this is the peer's certificate chain and, for clients, the server's certificate and temporary key. CERT holds only those values that can have meaningful defaults in an SSL_CTX.

    Bodo Moeller

    • New function X509V3_EXT_i2d() to create an X509_EXTENSION structure from the internal representation. Various PKCS#7 fixes: remove some evil casts and set the enc_dig_alg field properly based on the signing key type.

    Steve Henson

    • Allow PKCS#12 password to be set from the command line or the environment. Let 'ca' get its config file name from the environment variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' and 'x509').

    Steve Henson

    • Allow certificate policies extension to use an IA5STRING for the organization field. This is contrary to the PKIX definition but VeriSign uses it and IE5 only recognises this form. Document 'x509' extension option.

    Steve Henson

    • Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, without disallowing inline assembler and the like for non-pedantic builds.

    Ben Laurie

    • Support Borland C++ builder.

    Janez Jere [email protected], modified by Ulf Möller

    • Support Mingw32.

    Ulf Möller

    • SHA-1 cleanups and performance enhancements.

    Andy Polyakov [email protected]

    • Sparc v8plus assembler for the bignum library.

    Andy Polyakov [email protected]

    • Accept any -xxx and +xxx compiler options in Configure.

    Ulf Möller

    • Update HPUX configuration.

    Anonymous

    • Add missing sk_<type>_unshift() function to safestack.h

    Ralf S. Engelschall

    • New function SSL_CTX_use_certificate_chain_file that sets the "extra_cert"s in addition to the certificate. (This makes sense only for "PEM" format files, as chains as a whole are not DER-encoded.)

    Bodo Moeller

    • Support verify_depth from the SSL API. x509_vfy.c had what can be considered an off-by-one-error: Its depth (which was not part of the external interface) was actually counting the number of certificates in a chain; now it really counts the depth.

    Bodo Moeller

    • Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used instead of X509err, which often resulted in confusing error messages since the error codes are not globally unique (e.g. an alleged error in ssl3_accept when a certificate didn't match the private key).

    • New function SSL_CTX_set_session_id_context that allows to set a default value (so that you don't need SSL_set_session_id_context for each connection using the SSL_CTX).

    Bodo Moeller

    • OAEP decoding bug fix.

    Ulf Möller

    • Support INSTALL_PREFIX for package builders, as proposed by David Harris.

    Bodo Moeller

    • New Configure options "threads" and "no-threads". For systems where the proper compiler options are known (currently Solaris and Linux), "threads" is the default.

    Bodo Moeller

    • New script util/mklink.pl as a faster substitute for util/mklink.sh.

    Bodo Moeller

    • Install various scripts to $(OPENSSLDIR)/misc, not to $(INSTALLTOP)/bin -- they shouldn't clutter directories such as /usr/local/bin.

    Bodo Moeller

    • "make linux-shared" to build shared libraries.

    Niels Poppe [email protected]

    • New Configure option no-<cipher> (rsa, idea, rc5, ...).

    Ulf Möller

    • Add the PKCS#12 API documentation to openssl.txt. Preliminary support for extension adding in x509 utility.

    Steve Henson

    • Remove NOPROTO sections and error code comments.

    Ulf Möller

    • Partial rewrite of the DEF file generator to now parse the ANSI prototypes.

    Steve Henson

    • New Configure options --prefix=DIR and --openssldir=DIR.

    Ulf Möller

    • Complete rewrite of the error code script(s). It is all now handled by one script at the top level which handles error code gathering, header rewriting and C source file generation. It should be much better than the old method: it now uses a modified version of Ulf's parser to read the ANSI prototypes in all header files (thus the old K&R definitions aren't needed for error creation any more) and do a better job of translating function codes into names. The old 'ASN1 error code embedded in a comment' is no longer necessary and it doesn't use .err files which have now been deleted. Also the error code call doesn't have to appear all on one line (which resulted in some large lines...).

    Steve Henson

    • Change #include filenames from <foo.h> to <openssl/foo.h>.

    Bodo Moeller

    • Change behaviour of ssl2_read when facing length-0 packets: Don't return 0 (which usually indicates a closed connection), but continue reading.

    Bodo Moeller

    • Fix some race conditions.

    Bodo Moeller

    • Add support for CRL distribution points extension. Add Certificate Policies and CRL distribution points documentation.

    Steve Henson

    • Move the autogenerated header file parts to crypto/opensslconf.h.

    Ulf Möller

    • Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of 8 of keying material. Merlin has also confirmed interop with this fix between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.

    Merlin Hughes [email protected]

    • Fix lots of warnings.

    Richard Levitte [email protected]

    • In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if the directory spec didn't end with a LIST_SEPARATOR_CHAR.

    Richard Levitte [email protected]

    • Fix problems with sizeof(long) == 8.

    Andy Polyakov [email protected]

    • Change functions to ANSI C.

    Ulf Möller

    • Fix typos in error codes.

    Martin Kraemer [email protected], Ulf Möller

    • Remove defunct assembler files from Configure.

    Ulf Möller

    • SPARC v8 assembler BIGNUM implementation.

    Andy Polyakov [email protected]

    • Support for Certificate Policies extension: both print and set. Various additions to support the r2i method this uses.

    Steve Henson

    • A lot of constification, and fix a bug in X509_NAME_oneline() that could return a const string when you are expecting an allocated buffer.

    Ben Laurie

    • Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE types DirectoryString and DisplayText.

    Steve Henson

    • Add code to allow r2i extensions to access the configuration database, add an LHASH database driver and add several ctx helper functions.

    Steve Henson

    • Fix an evil bug in bn_expand2() which caused various BN functions to fail when they extended the size of a BIGNUM.

    Steve Henson

    • Various utility functions to handle SXNet extension. Modify mkdef.pl to support typesafe stack.

    Steve Henson

    • Fix typo in SSL_[gs]et_options().

    Nils Frostberg [email protected]

    • Delete various functions and files that belonged to the (now obsolete) old X509V3 handling code.

    Steve Henson

    • New Configure option "rsaref".

    Ulf Möller

    • Don't auto-generate pem.h.

    Bodo Moeller

    • Introduce type-safe ASN.1 SETs.

    Ben Laurie

    • Convert various additional casted stacks to type-safe STACK_OF() variants.

    Ben Laurie, Ralf S. Engelschall, Steve Henson

    • Introduce type-safe STACKs. This will almost certainly break lots of code that links with OpenSSL (well at least cause lots of warnings), but fear not: the conversion is trivial, and it eliminates loads of evil casts. A few STACKed things have been converted already. Feel free to convert more. In the fullness of time, I'll do away with the STACK type altogether.

    Ben Laurie

    • Add openssl ca -revoke <certfile> facility which revokes a certificate specified in <certfile> by updating the entry in the index.txt file. This way one no longer has to edit the index.txt file manually for revoking a certificate. The -revoke option does the gory details now.

    Massimiliano Pala [email protected], Ralf S. Engelschall

    • Fix openssl crl -noout -text combination where -noout killed the -text option at all and this way the -noout -text combination was inconsistent in openssl crl with the friends in openssl x509|rsa|dsa.

    Ralf S. Engelschall

    • Make sure a corresponding plain text error message exists for the X509_V_ERR_CERT_REVOKED/23 error number which can occur when a verify callback function determined that a certificate was revoked.

    Ralf S. Engelschall

    • Bugfix: In test/testenc, don't test openssl <cipher> for ciphers that were excluded, e.g. by -DNO_IDEA. Also, test all available ciphers including rc5, which was forgotten until now. In order to let the testing shell script know which algorithms are available, a new (up to now undocumented) command openssl list-cipher-commands is used.

    Bodo Moeller

    • Bugfix: s_client occasionally would sleep in select() when it should have checked SSL_pending() first.

    Bodo Moeller

    • New functions DSA_do_sign and DSA_do_verify to provide access to the raw DSA values prior to ASN.1 encoding.

    Ulf Möller

    • Tweaks to Configure

    Niels Poppe [email protected]

    • Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, yet...

    Steve Henson

    • New variables $(RANLIB) and $(PERL) in the Makefiles.

    Ulf Möller

    • New config option to avoid instructions that are illegal on the 80386. The default code is faster, but requires at least a 486.

    Ulf Möller

    • Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and SSL2_SERVER_VERSION (not used at all) macros, which are now the same as SSL2_VERSION anyway.

    Bodo Moeller

    • New "-showcerts" option for s_client.

    Bodo Moeller

    • Still more PKCS#12 integration. Add pkcs12 application to openssl application. Various cleanups and fixes.

    • More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and modify error routines to work internally. Add error codes and PBE init to library startup routines.

    Steve Henson

    • Further PKCS#12 integration. Added password based encryption, PKCS#8 and packing functions to asn1 and evp. Changed function names and error codes along the way.

    Steve Henson

    • PKCS12 integration: and so it begins... First of several patches to slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 objects to objects.h

    Steve Henson

    • Add a new 'indent' option to some X509V3 extension code. Initial ASN1 and display support for Thawte strong extranet extension.

    Steve Henson

    • Add LinuxPPC support.

    Jeff Dubrule [email protected]

    • Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to bn_div_words in alpha.s.

    Hannes Reinecke [email protected] and Ben Laurie

    • Make sure the RSA OAEP test is skipped under -DRSAref because OAEP isn't supported when OpenSSL is built with RSAref.

    Ulf Moeller [email protected]

    • Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h so they no longer are missing under -DNOPROTO.

    Soren S. Jorvang [email protected]

  • v0.9.1.c Changes

    March 22, 1999
    • Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still doesn't work when the session is reused. Coming soon!

    Ben Laurie

    • Fix a security hole, that allows sessions to be reused in the wrong context thus bypassing client cert protection! All software that uses client certs and session caches in multiple contexts NEEDS PATCHING to allow session reuse! A fuller solution is in the works.

    Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)

    • Some more source tree cleanups (removed obsolete files crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed permission on "config" script to be executable) and a fix for the INSTALL document.

    Ulf Moeller [email protected]

    • Remove some legacy and erroneous uses of malloc, free instead of Malloc, Free.

    Lennart Bang [email protected], with minor changes by Steve

    • Make rsa_oaep_test return non-zero on error.

    Ulf Moeller [email protected]

    • Add support for native Solaris shared libraries. Configure solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice if someone would make that last step automatic.

    Matthias Loepfe [email protected]

    • ctx_size was not built with the right compiler during "make links". Fixed.

    Ben Laurie

    • Change the meaning of 'ALL' in the cipher list. It now means "everything except NULL ciphers". This means the default cipher list will no longer enable NULL ciphers. They need to be specifically enabled e.g. with the string "DEFAULT:eNULL".

    Steve Henson

    • Fix to RSA private encryption routines: if p < q then it would occasionally produce an invalid result. This will only happen with externally generated keys because OpenSSL (and SSLeay) ensure p > q.

    Steve Henson

    • Be less restrictive and allow also perl util/perlpath.pl /path/to/bin/perl in addition to perl util/perlpath.pl /path/to/bin, because this way one can also use an interpreter named perl5 (which is usually the name of Perl 5.xxx on platforms where an Perl 4.x is still installed as perl).

    Matthias Loepfe [email protected]

    • Let util/clean-depend.pl work also with older Perl 5.00x versions.

    Matthias Loepfe [email protected]

    • Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add advapi32.lib to Win32 build and change the pem test comparison to fc.exe (thanks to Ulrich Kroener [email protected] for the suggestion). Fix misplaced ASNI prototypes and declarations in evp.h and crypto/des/ede_cbcm_enc.c.

    Steve Henson

    • DES quad checksum was broken on big-endian architectures. Fixed.

    Ben Laurie

    • Comment out two functions in bio.h that aren't implemented. Fix up the Win32 test batch file so it (might) work again. The Win32 test batch file is horrible: I feel ill....

    Steve Henson

    • Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected in e_os.h. Audit of header files to check ANSI and non ANSI sections: 10 functions were absent from non ANSI section and not exported from Windows DLLs. Fixed up libeay.num for new functions.

    Steve Henson

    • Make openssl version output lines consistent.

    Ralf S. Engelschall

    • Fix Win32 symbol export lists for BIO functions: Added BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data to ms/libeay{16,32}.def.

    Ralf S. Engelschall

    • Second round of fixing the OpenSSL perl/ stuff. It now at least compiled fine under Unix and passes some trivial tests I've now added. But the whole stuff is horribly incomplete, so a README.1ST with a disclaimer was added to make sure no one expects that this stuff really works in the OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and openssl_bio.xs.

    Ralf S. Engelschall

    • Fix the generation of two part addresses in perl.

    Kenji Miyake [email protected], integrated by Ben Laurie

    • Add config entry for Linux on MIPS.

    John Tobey [email protected]

    • Make links whenever Configure is run, unless we are on Windoze.

    Ben Laurie

    • Permit extensions to be added to CRLs using crl_section in openssl.cnf. Currently only issuerAltName and AuthorityKeyIdentifier make any sense in CRLs.

    Steve Henson

    • Add a useful kludge to allow package maintainers to specify compiler and other platforms details on the command line without having to patch the Configure script every time: One now can use perl Configure <id>:<details>, i.e. platform ids are allowed to have details appended to them (separated by colons). This is treated as there would be a static pre-configured entry in Configure's %table under key <id> with value <details> and perl Configure <id> is called. So, when you want to perform a quick test-compile under FreeBSD 3.1 with pgcc and without assembler stuff you can use perl Configure "FreeBSD-elf:pgcc:-O6:::" now, which overrides the FreeBSD-elf entry on-the-fly.

    Ralf S. Engelschall

    • Disable new TLS1 ciphersuites by default: they aren't official yet.

    Ben Laurie

    • Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified on the perl Configure ... command line. This way one can compile OpenSSL libraries with Position Independent Code (PIC) which is needed for linking it into DSOs.

    Ralf S. Engelschall

    • Remarkably, export ciphers were totally broken and no-one had noticed! Fixed.

    Ben Laurie

    • Cleaned up the LICENSE document: The official contact for any license questions now is the OpenSSL core team under [email protected]. And add a paragraph about the dual-license situation to make sure people recognize that BOTH the OpenSSL license AND the SSLeay license apply to the OpenSSL toolkit.

    Ralf S. Engelschall

    • General source tree makefile cleanups: Made making xxx in yyy... display consistent in the source tree and replaced /bin/rm by rm. Additionally cleaned up the make links target: Remove unnecessary semicolons, subsequent redundant removes, inline point.sh into mklink.sh to speed processing and no longer clutter the display with confusing stuff. Instead only the actually done links are displayed.

    Ralf S. Engelschall

    • Permit null encryption ciphersuites, used for authentication only. It used to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. It is now necessary to set SSL_FORBID_ENULL to prevent the use of null encryption.

    Ben Laurie

    • Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder signed attributes when verifying signatures (this would break them), the detached data encoding was wrong and public keys obtained using X509_get_pubkey() weren't freed.

    Steve Henson

    • Add text documentation for the BUFFER functions. Also added a work around to a Win95 console bug. This was triggered by the password read stuff: the last character typed gets carried over to the next fread(). If you were generating a new cert request using 'req' for example then the last character of the passphrase would be CR which would then enter the first field as blank.

    Steve Henson

    • Added the new 'Includes OpenSSL Cryptography Software' button as doc/openssl_button.{gif,html} which is similar in style to the old SSLeay button and can be used by applications based on OpenSSL to show the relationship to the OpenSSL project.

    Ralf S. Engelschall

    • Remove confusing variables in function signatures in files ssl/ssl_lib.c and ssl/ssl.h.

    Lennart Bong [email protected]

    • Don't install bss_file.c under PREFIX/include/

    Lennart Bong [email protected]

    • Get the Win32 compile working again. Modify mkdef.pl so it can handle functions that return function pointers and has support for NT specific stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various #ifdef WIN32 and WINNTs sprinkled about the place and some changes from unsigned to signed types: this was killing the Win32 compile.

    Steve Henson

    • Add new certificate file to stack functions, SSL_add_dir_cert_subjects_to_stack() and SSL_add_file_cert_subjects_to_stack(). These largely supplant SSL_load_client_CA_file(), and can be used to add multiple certs easily to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). This means that Apache-SSL and similar packages don't have to mess around to add as many CAs as they want to the preferred list.

    Ben Laurie

    Ben Laurie

    • Get rid of remaining C++-style comments which strict C compilers hate.

    Ralf S. Engelschall, pointed out by Carlos Amengual

    • Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not compiled in by default: it has problems with large keys.

    Steve Henson

    • Add a bunch of SSL_xxx() functions for configuring the temporary RSA and DH private keys and/or callback functions which directly correspond to their SSL_CTX_xxx() counterparts but work on a per-connection basis. This is needed for applications which have to configure certificates on a per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis (e.g. s_server). For the RSA certificate situation is makes no difference, but for the DSA certificate situation this fixes the "no shared cipher" problem where the OpenSSL cipher selection procedure failed because the temporary keys were not overtaken from the context and the API provided no way to reconfigure them. The new functions now let applications reconfigure the stuff and they are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new non-public-API function ssl_cert_instantiate() is used as a helper function and also to reduce code redundancy inside ssl_rsa.c.

    Ralf S. Engelschall

    • Move s_server -dcert and -dkey options out of the undocumented feature area because they are useful for the DSA situation and should be recognized by the users.

    Ralf S. Engelschall

    • Fix the cipher decision scheme for export ciphers: the export bits are not within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within SSL_EXP_MASK. So, the original variable has to be used instead of the already masked variable.

    Richard Levitte [email protected]

    • Fix port variable from int to unsigned int in crypto/bio/b_sock.c

    Richard Levitte [email protected]

    • Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() from int to unsigned int because it is a length and initialized by EVP_DigestFinal() which expects an unsigned int *.

    Richard Levitte [email protected]

    • Don't hard-code path to Perl interpreter on shebang line of Configure script. Instead use the usual Shell->Perl transition trick.

    Ralf S. Engelschall

    • Make openssl x509 -noout -modulus' functional also for DSA certificates (in addition to RSA certificates) to match the behaviour of openssl dsa -noout -modulus as it's already the case for openssl rsa -noout -modulus. For RSA the -modulus is the real "modulus" while for DSA currently the public key is printed (a decision which was already done by openssl dsa -modulus in the past) which serves a similar purpose. Additionally the NO_RSA no longer completely removes the whole -modulus option; it now only avoids using the RSA stuff. Same applies to NO_DSA now, too.

    Ralf S. Engelschall

    • Add Arne Ansper's reliable BIO - this is an encrypted, block-digested BIO. See the source (crypto/evp/bio_ok.c) for more info.

    Arne Ansper [email protected]

    • Dump the old yucky req code that tried (and failed) to allow raw OIDs to be added. Now both 'req' and 'ca' can use new objects defined in the config file.

    Steve Henson

    • Add cool BIO that does syslog (or event log on NT).

    Arne Ansper [email protected], integrated by Ben Laurie

    • Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.

    Ben Laurie

    • Add preliminary config info for new extension code.

    Steve Henson

    • Make RSA_NO_PADDING really use no padding.

    Ulf Moeller [email protected]

    • Generate errors when private/public key check is done.

    Ben Laurie

    • Overhaul for 'crl' utility. New function X509_CRL_print. Partial support for some CRL extensions and new objects added.

    Steve Henson

    • Really fix the ASN1 IMPLICIT bug this time... Partial support for private key usage extension and fuller support for authority key id.

    Steve Henson

    • Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved padding method for RSA, which is recommended for new applications in PKCS

      1 v2.0 (RFC 2437, October 1998).

      OAEP (Optimal Asymmetric Encryption Padding) has better theoretical foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure against Bleichbacher's attack on RSA. Ulf Moeller [email protected], reformatted, corrected and integrated by Ben Laurie

    • Updates to the new SSL compression code

    Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)

    • Fix so that the version number in the master secret, when passed via RSA, checks that if TLS was proposed, but we roll back to SSLv3 (because the server will not accept higher), that the version number is 0x03,0x01, not 0x03,0x00

    Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)

    • Run extensive memory leak checks on SSL commands. Fixed lots of memory leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c.

    Steve Henson

    • Support for RAW extensions where an arbitrary extension can be created by including its DER encoding. See apps/openssl.cnf for an example.

    Steve Henson

    • Make sure latest Perl versions don't interpret some generated C array code as Perl array code in the crypto/err/err_genc.pl script.

    Lars Weber [email protected]

    • Modify ms/do_ms.bat to not generate assembly language makefiles since not many people have the assembler. Various Win32 compilation fixes and update to the INSTALL.W32 file with (hopefully) more accurate Win32 build instructions.

    Steve Henson

    • Modify configure script 'Configure' to automatically create crypto/date.h file under Win32 and also build pem.h from pem.org. New script util/mkfiles.pl to create the MINFO file on environments that can't do a 'make files': perl util/mkfiles.pl >MINFO should work.

    Steve Henson

    • Major rework of DES function declarations, in the pursuit of correctness and purity. As a result, many evil casts evaporated, and some weirdness, too. You may find this causes warnings in your code. Zapping your evil casts will probably fix them. Mostly.

    Ben Laurie

    • Fix for a typo in asn1.h. Bug fix to object creation script obj_dat.pl. It considered a zero in an object definition to mean "end of object": none of the objects in objects.h have any zeros so it wasn't spotted.

    Steve Henson, reported by Erwann ABALEA [email protected]

    • Add support for Triple DES Cipher Block Chaining with Output Feedback Masking (CBCM). In the absence of test vectors, the best I have been able to do is check that the decrypt undoes the encrypt, so far. Send me test vectors if you have them.

    Ben Laurie

    • Correct calculation of key length for export ciphers (too much space was allocated for null ciphers). This has not been tested!

    Ben Laurie

    • Modifications to the mkdef.pl for Win32 DEF file creation. The usage message is now correct (it understands "crypto" and "ssl" on its command line). There is also now an "update" option. This will update the util/ssleay.num and util/libeay.num files with any new functions. If you do a: perl util/mkdef.pl crypto ssl update it will update them.

    Steve Henson

    • Overhauled the Perl interface:
      • ported BN stuff to OpenSSL's different BN library
      • made the perl/ source tree CVS-aware
      • renamed the package from SSLeay to OpenSSL (the files still contain their history because I've copied them in the repository)
      • removed obsolete files (the test scripts will be replaced by better Test::Harness variants in the future)

    Ralf S. Engelschall

    • First cut for a very conservative source tree cleanup:
      1. merge various obsolete readme texts into doc/ssleay.txt where we collect the old documents and readme texts.
      2. remove the first part of files where I'm already sure that we no longer need them because of three reasons: either they are just temporary files which were left by Eric or they are preserved original files where I've verified that the diff is also available in the CVS via "cvs diff -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for the crypto/md/ stuff).

    Ralf S. Engelschall

    • More extension code. Incomplete support for subject and issuer alt name, issuer and authority key id. Change the i2v function parameters and add an extra 'crl' parameter in the X509V3_CTX structure: guess what that's for :-) Fix to ASN1 macro which messed up IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.

    Steve Henson

    • Preliminary support for ENUMERATED type. This is largely copied from the INTEGER code.

    Steve Henson

    • Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.

    Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)

    • Make sure make rehash target really finds the openssl program.

    Ralf S. Engelschall, Matthias Loepfe [email protected]

    • Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd like to hear about it if this slows down other processors.

    Ben Laurie

    • Add CygWin32 platform information to Configure script.

    Alan Batie [email protected]

    • Fixed ms/32all.bat script: no_asm -> no-asm

    Rainer W. Gerling [email protected]

    • New program nseq to manipulate netscape certificate sequences

    Steve Henson

    • Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a few typos.

    Steve Henson

    • Fixes to BN code. Previously the default was to define BN_RECURSION but the BN code had some problems that would cause failures when doing certificate verification and some other functions.

    Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)

    • Add ASN1 and PEM code to support netscape certificate sequences.

    Steve Henson

    • Add ASN1 and PEM code to support netscape certificate sequences.

    Steve Henson

    • Add several PKIX and private extended key usage OIDs.

    Steve Henson

    • Modify the 'ca' program to handle the new extension code. Modify openssl.cnf for new extension format, add comments.

    Steve Henson

    • More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' and add a sample to openssl.cnf so req -x509 now adds appropriate CA extensions.

    Steve Henson

    • Continued X509 V3 changes. Add to other makefiles, integrate with the error code, add initial support to X509_print() and x509 application.

    Steve Henson

    • Takes a deep breath and start adding X509 V3 extension support code. Add files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this stuff is currently isolated and isn't even compiled yet.

    Steve Henson

    • Continuing patches for GeneralizedTime. Fix up certificate and CRL ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. Removed the versions check from X509 routines when loading extensions: this allows certain broken certificates that don't set the version properly to be processed.

    Steve Henson

    • Deal with irritating shit to do with dependencies, in YAAHW (Yet Another Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which can still be regenerated with "make depend".

    Ben Laurie

    • Spelling mistake in C version of CAST-128.

    Ben Laurie, reported by Jeremy Hylton [email protected]

    • Changes to the error generation code. The perl script err-code.pl now reads in the old error codes and retains the old numbers, only adding new ones if necessary. It also only changes the .err files if new codes are added. The makefiles have been modified to only insert errors when needed (to avoid needlessly modifying header files). This is done by only inserting errors if the .err file is newer than the auto generated C file. To rebuild all the error codes from scratch (the old behaviour) either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl or delete all the .err files.

    Steve Henson

    • CAST-128 was incorrectly implemented for short keys. The C version has been fixed, but is untested. The assembler versions are also fixed, but new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing to regenerate it if needed. Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun Hagino [email protected]

    • File was opened incorrectly in randfile.c.

    Ulf Möller [email protected]

    • Beginning of support for GeneralizedTime. d2i, i2d, check and print functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or GeneralizedTime. ASN1_TIME is the proper type used in certificates et al: it's just almost always a UTCTime. Note this patch adds new error codes so do a "make errors" if there are problems.

    Steve Henson

    • Correct Linux 1 recognition in config.

    Ulf Möller [email protected]

    • Remove pointless MD5 hash when using DSA keys in ca.

    Anonymous [email protected]

    • Generate an error if given an empty string as a cert directory. Also generate an error if handed NULL (previously returned 0 to indicate an error, but didn't set one).

    Ben Laurie, reported by Anonymous [email protected]

    • Add prototypes to SSL methods. Make SSL_write's buffer const, at last.

    Ben Laurie

    • Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct parameters. This was causing a warning which killed off the Win32 compile.

    Steve Henson

    • Remove C++ style comments from crypto/bn/bn_local.h.

    Neil Costigan [email protected]

    • The function OBJ_txt2nid was broken. It was supposed to return a nid based on a text string, looking up short and long names and finally "dot" format. The "dot" format stuff didn't work. Added new function OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the OID is not part of the table.

    Steve Henson

    • Add prototypes to X509 lookup/verify methods, fixing a bug in X509_LOOKUP_by_alias().

    Ben Laurie

    • Make all *_free functions accept a NULL pointer.

    Frans Heymans [email protected]

    • If a DH key is generated in s3_srvr.c, don't blow it by trying to use NULL pointers.

    Anonymous [email protected]

    • s_server should send the CAfile as acceptable CAs, not its own cert.

    Bodo Moeller [email protected]

    • Don't blow it for numeric -newkey arguments to apps/req.

    Bodo Moeller [email protected]

    • Temp key "for export" tests were wrong in s3_srvr.c.

    Anonymous [email protected]

    • Add prototype for temp key callback functions SSL_CTX_set_tmp_{rsa,dh}_callback().

    Ben Laurie

    • Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().

    Steve Henson

    • X509_name_add_entry() freed the wrong thing after an error.

    Arne Ansper [email protected]

    • rsa_eay.c would attempt to free a NULL context.

    Arne Ansper [email protected]

    • BIO_s_socket() had a broken should_retry() on Windoze.

    Arne Ansper [email protected]

    • BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.

    Arne Ansper [email protected]

    • Make sure the already existing X509_STORE->depth variable is initialized in X509_STORE_new(), but document the fact that this variable is still unused in the certificate verification process.

    Ralf S. Engelschall

    • Fix the various library and apps/ files to free up pkeys obtained from X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.

    Steve Henson

    • Fix reference counting in X509_PUBKEY_get(). This makes demos/maurice/example2.c work, amongst others, probably.

    Steve Henson and Ben Laurie

    • First cut of a cleanup for apps/. First the ssleay program is now named openssl and second, the shortcut symlinks for the openssl <command> are no longer created. This way we have a single and consistent command line interface openssl <command>, similar to cvs <command>.

    Ralf S. Engelschall, Paul Sutton and Ben Laurie

    • ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey BIT STRING wrapper always have zero unused bits.

    Steve Henson

    • Add CA.pl, perl version of CA.sh, add extended key usage OID.

    Steve Henson

    • Make the top-level INSTALL documentation easier to understand.

    Paul Sutton

    • Makefiles updated to exit if an error occurs in a sub-directory make (including if user presses C) [Paul Sutton]

    • Make Montgomery context stuff explicit in RSA data structure.

    Ben Laurie

    • Fix build order of pem and err to allow for generated pem.h.

    Ben Laurie

    • Fix renumbering bug in X509_NAME_delete_entry().

    Ben Laurie

    • Enhanced the err-ins.pl script so it makes the error library number global and can add a library name. This is needed for external ASN1 and other error libraries.

    Steve Henson

    • Fixed sk_insert which never worked properly.

    Steve Henson

    • Fix ASN1 macros so they can handle indefinite length constructed EXPLICIT tags. Some non standard certificates use these: they can now be read in.

    Steve Henson

    • Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) into a single doc/ssleay.txt bundle. This way the information is still preserved but no longer messes up this directory. Now it's new room for the new set of documentation files.

    Ralf S. Engelschall

    • SETs were incorrectly DER encoded. This was a major pain, because they shared code with SEQUENCEs, which aren't coded the same. This means that almost everything to do with SETs or SEQUENCEs has either changed name or number of arguments.

    Ben Laurie, based on a partial fix by GP Jayan [email protected]

    • Fix test data to work with the above.

    Ben Laurie
