Fast AES cipher implementation with advanced mode of operations
Fast AES cipher implementation with advanced mode of operations. The modes of operations available are ECB Electronic code book, CBC Cipher block chaining, CTR Counter, XTS XEX with ciphertext stealing, GCM Galois Counter Mode. The AES implementation uses AES-NI when available on x86 and x86-64 architecture, but fallback gracefully to a software C implementation. The software implementation uses S-Boxes, which might suffer for cache timing issues. However do notes that most other known software implementations, including very popular one openssl, gnutls also uses same implementation. If it matters for your case, you should make sure you have AES-NI available, or you’ll need to use a different implementation.
