    🔋 Features

    • Parsing of PKCS#8 encrypted private key files
    • PKCS#12 PBE and derivation functions

    • HAVEGE random generator disabled by default
    • Internally split up x509parse_key() into a (PEM) handler function and specific DER parser functions for the PKCS#1 and unencrypted PKCS#8 private key formats
    • Added mechanism to provide alternative implementations for all symmetric cipher and hash algorithms (e.g. POLARSSL_AES_ALT in config.h)
    • PKCS#5 module added. Moved PBKDF2 functionality inside and deprecated old PBKDF2 module

    🛠 Bugfix

    • Secure renegotiation extension should only be sent in case client supports secure renegotiation
