AOCL-Cryptography

The AOCL-Cryptography library consists of core cryptographic functions optimized for AMD “Zen” micro-architecture. It supports multiple cryptographic routines and enables provider path for the following routines:

• Advanced Encryption Standard (AES) block ciphers—CTR, CFB, GCM, OFB, XTS, SIV
• ChaCha20 stream cipher, Chacha20-Poly1305 Cipher algorithms
• Cipher, Hash, and Poly1305 based Message Authentication Code (MAC) algorithms
• Elliptic-curve Diffie-Hellman (ECDH) Key Generation algorithms
• Rivest, Shamir, and Adleman (RSA) encryption/decryption and sign/verify algorithms

Highlights of AOCL-Cryptography 5.2

• Performance improvements to SHA3, SHA256, and GCM AVX512
• Multi-buffer support for CBC and CFB
• In-place buffer support for Ciphers
• Supports OpenSSL 3.5 (experimental support)
• Supports Clang 19 and GCC 14
• Fixed all high-severity Coverity defects and addressed a majority of medium-severity defects
• Benchmarking and test framework improvements

Poly-ChaCha will exhibit unexpected behavior on AVX512 machines that do not support the IFMA (Integer Fused Multiply-Add) instruction set
