     If your secret key is pqrstuv, the lowest number it combines with to make an MD5 hash starting with five zeroes is 1048970; that is, the MD5 hash of pqrstuv1048970 looks like 000006136ef....
 
 Your puzzle input is yzbqklnj.

+I'm going to use the RFC 1321 library here, as designing an md5 implementation is a bit too much for right now
+Correction, I will use the old style openssl/md5.h
