How can I interpret openssl speed output?

Question

I ran openssl speed on my Ubuntu computer. Some results:

Doing md4 for 3s on 16 size blocks: 9063888 md4\'s in 3.00s
Doing md4 for 3s on 64 size blo         


        

Answer 1

While it could probably be worded better, it pretty much means what it says - run the md4 hash routine in a loop for 3 seconds with a 16 byte input. After 3 seconds, observe that we ran just a bit over 9 million iterations. That's about 144 million bytes processed, or 48 million bytes per second (where "million" means 10^6).
