Check openssl for AES-NI

How to check if hardware support for encryption is enabled and working?

Run those two commands:

openssl speed -elapsed -evp aes-128-cbc
OPENSSL_ia32cap="~0x200000200000000" openssl speed -elapsed -evp aes-128-cbc

The first results are much faster if AES-NI is working. Otherwise they should be similar.
