This benchmark is a mix of 2007/2010/2013 test vectors, right?

Cool. Sounds like a candidate for a tweet!

I could give it a shot. I gets complicated as you support three different types in one format (although that's easier for the user).
So 2013 is SHA512 + AES and 2010 is SHA1 + AES, right? And, um... 2007 is also SHA1 + AES but using another scheme? I could start with 2007/2010 I guess.
