What have the GNU people done to get the speed out of the code? I've tried to call the md5_stream function directly and got ~13-14 seconds. I've approximated the md5_stream function from the md5.h library into the code below, and it runs in ~13-14 seconds. After analysing the source code, it seems that md5sum relies on the md5 library's md5_stream. I've been studying hashing in C/C++ and tried to replicate the md5sum command in Linux.
