Fast AES cipher implementation; profiling libraries

 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 note 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.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
