+Description:
+    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.
+    .
