wolfEngine Release 1.4.0 (November 2, 2023)

• Added calls to PRIVATE_KEY_UNLOCK() and PRIVATE_KEY_LOCK() as needed.
• Allow user to override weak entropy source.

wolfEngine Release 1.3.0 (January 16, 2023)

• Added RPM package support
• Added support and tests for OpenSSL HMAC to be called with -1 key length
• Updated examples to support use with OpenSSL 1.0.2

wolfEngine Release 1.2.0 (September 29, 2022)

• ChangeLog.md is now shipped with releases.
• Random number generation now mixes in some additional weak entropy (e.g. PID)
  to ensure unique numbers, even if the RNG state is copied into a forked process.
• Using wolfEngine with the wolfSSL FIPS 140-3 candidate code will now work as
  intended in multi-threaded Windows applications. This was accomplished by adding
  a DllMain function that calls wolfCrypt_SetPrivateKeyReadEnable_fips on new
  thread creation.
• The RSA code now supports the rsa_keygen_pubexp control command string.
• The RSA code now has a verify_recover function.
• The automake code was adjusted to support builds not in the project root. This
  is particularly useful for Yocto builds.
• The Visual Studio solution now has configurations to support the wolfSSL FIPS
  140-3 candidate code.
• The random bytes function will now return success and do nothing if the
  provided length is 0.
• Fixed a potential seg fault in we_dh_compute_key_int if DH_get0_priv_key
  returned NULL.
• The DH code now supports the dh_paramgen_prime_len control command string.
• Attempting to use the control command EVP_PKEY_CTRL_DH_PARAMGEN_GENERATOR
  will now return an error, as wolfCrypt doesn't support setting the generator for
  DH.

wolfEngine Release 1.1.0 (May 16, 2022)

• Updated README.md to refer to new wolfSSL configure flag --enable-engine.
• Fixed a double free bug in certain error cases in the ECC code.
• Added examples/ and engine.conf to the distribution.
• Fixed a bug in the AES-CTR implementation where partial block data from a
  previous operation would leak into the current operation, even when the IV was
  changed between operations.
• Added support for X9.31 padding with RSA signatures.

wolfEngine Release 1.0.0 (Mar 7, 2022)

• Added the examples/ directory.
• Added logic to openssl-unit-tests.sh to support macOS.
• Reworked the AES-GCM implementation to support all OpenSSL use cases. Added a
  unit test to exercise AES-GCM with the EVP_Cipher() API.
• Made some error return codes in the ECC code consistent with OpenSSL.
• Fixed some OpenSSL version gates in the ECC code.
• Adjusted wolfEngine initialization code to support FIPS v5 (140-3).
• Added control commands for enabling wolfSSL debug logging and setting the
  wolfSSL debug log callback.
• Added a FIPS integrity check callback so that if the check fails, it's
  reported to the user, along with the necessary hash value.
• Improved Visual Studio support.
• Added some additional HMAC functions that were needed when running the OpenSSL
  1.1.1m unit tests with wolfEngine.

wolfEngine Release 0.9.0 (Nov 12, 2021)

This is the first official release of wolfEngine. Please refer to README.md for more information.
