libsodium v1.0.17 Release Notes

Release Date: 2019-01-07 // over 5 years ago
    • 🐛 Bug fix: sodium_pad() didn't properly support block sizes >= 256 bytes.
    • JS/WebAssembly: some old iOS versions can't instantiate the WebAssembly module; fall back to Javascript on these.
    • JS/WebAssembly: compatibility with newer Emscripten versions.
    • Bug fix: crypto_pwhash_scryptsalsa208sha256_str_verify() and crypto_pwhash_scryptsalsa208sha256_str_needs_rehash()didn't returnEINVAL` on input strings with a short length, unlike their high-level counterpart.
    • ➕ Added a workaround for Visual Studio 2010 bug causing CPU features not to be detected.
    • Portability improvements.
    • ✅ Test vectors from Project Wycheproof have been added.
    • 🆕 New low-level APIs for arithmetic mod the order of the prime order group:
      crypto_core_ed25519_scalar_random(), crypto_core_ed25519_scalar_reduce(),
      crypto_core_ed25519_scalar_invert(), crypto_core_ed25519_scalar_negate(),
      crypto_core_ed25519_scalar_complement(), crypto_core_ed25519_scalar_add() and crypto_core_ed25519_scalar_sub().
    • New low-level APIs for scalar multiplication without clamping: crypto_scalarmult_ed25519_base_noclamp() and crypto_scalarmult_ed25519_noclamp(). These new APIs are especially useful for blinding.
    • sodium_sub() has been implemented.
    • 👌 Support for WatchOS has been added.
    • getrandom(2) is now used on FreeBSD 12+.
    • The nonnull attribute has been added to all relevant prototypes.
    • More reliable AVX512 detection.
    • 🏗 Javascript/Webassembly builds now use dynamic memory growth.
