The Intel Advanced Encryption Standard (AES) or New Instructions (AES-NI) engine enables extremely fast hardware encryption and decryption for openssl, ssh, vpn, Linux/Unix/OSX full disk encryption and more. How do I check support for Intel or AMD AES-NI is loaded in my running Linux in my Linux based system including openssl?
