+
+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 similar
+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.")
