Mbed Crypto change history

Unreleased changes

Interface changes

  • In the PSA API, forbid zero-length keys. To pass a zero-length input to a key derivation function, use a buffer instead (this is now always possible).

New features

  • Key derivation inputs in the PSA API can now either come from a key object or from a buffer regardless of the step type.

Bug fixes

  • Fix a buffer overflow in the PSA HMAC code when using a long key with an unsupported algorithm. Fixes #254.
  • Fix mbedtls_asn1_get_int to support any number of leading zeros.
  • Fix mbedtls_asn1_get_bitstring_null to correctly parse bitstrings of at most 2 bytes.

Performance improvements

  • Remove a useless call to mbedtls_ecp_group_free(). Contributed by Alexander Krizhanovsky in #210.
  • Speed up PBKDF2 by caching the digest calculation. Contributed by Jack Lloyd and Fortanix Inc in #277.

Other changes

  • Remove the technical possibility to define custom md_info structures, which was exposed only in an internal header.
