Compatability with previous versions is maintained. The documentation has been updated accordingly. GH #457 and #567 +* How the library presents optimized algorithm implementations has changed. For + example with the algorithm AES-128, previously there were three BlockCipher + classes AES_128, AES_128_SSSE3, and AES_128_NI which used (resp) a table-based + implementation vulnerable to side channels, a constant time version using + SSSE3 SIMD extensions on modern x86, and x86 AES-NI instructions. Using the + correct version at runtime required using `BlockCipher::create`. Now, only the + class AES_128 is presented, and the best available version is always used + based on CPUID checks. The tests have been extended to selectively disable + CPUID bits to ensure all available versions are tested. + + Removes API classes AES_128_NI, AES_192_NI, AES_256_NI, AES_128_SSSE3, + AES_192_SSSE3 AES_256_SSSE3, IDEA_SSE2, Noekeon_SIMD, Serpent_SIMD, + Threefish_512_AVX2, SHA_160_SSE2 + + GH #477 #623 + * The deprecated algorithms Rabin-Williams, Nyberg-Rueppel, MARS, RC2, RC5, RC6, SAFER-SK, TEA, MD2, HAS-160, and RIPEMD-128 have been removed.
