I was also thinking of trying to profile the program as a first step in increasing its performance in general; that might reveal something interesting as well. I am also planning to write a similar program in C using OpenSSL's Blowfish implementation. I want to get a point of comparison to see if my implementation has "reasonable" performance or not (here I'm assuming that OpenSSL is reasonable). I'm curious now if the C/OpenSSL version will also demonstrate this same performance quirk. Peter
