Pure Rust implementation of the AES-SIV Misuse-Resistant Authenticated Encryption Cipher (RFC 5297) with optional architecture-specific hardware acceleration

eaxcrates.ioPure Rust implementation of the EAX Authenticated Encryption with Associated Data (AEAD) Cipher with optional architecture-specific hardware acceleration. Implemented generically around block ciphers, it combines counter mode (CTR) encryption with CMAC authentication.
