Just to get a little indication of the "smidge" better performance of 
hardware accelerated AES.

This is what i get for AES on Core i7 4770 (a.k.a. Haswell)

#  Algorithm | Key |  Encryption |  Decryption
     aes-cbc   128b   753.2 MiB/s  3305.0 MiB/s
     aes-cbc   256b   551.4 MiB/s  2509.0 MiB/s
     aes-xts   256b  2799.0 MiB/s  2853.0 MiB/s
     aes-xts   512b  2154.0 MiB/s  2162.0 MiB/s
