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.")
