Creating MD5 hashs?

is there a simple way to make MD5 hashs in c++? i know there is in languages like php

is there a simple way to do it? or would i have to use an algorithm?

MD5 is an algorithm. There is no standard MD5 hash function, but you can use a cryptographic library such as Botan or Crypto++, or implement it yourself.

Thanks, from what i can see from those Botan or Crypto++, sites thats what i am looking for... Cheers

Incidentally, you might want to note that MD5 is classified by Crypto++ as being an "insecure or obsolescent algorithms retained for backwards compatibility and historical value".

But it's not really used for security too much anyway (besides web applications), usually it's just used as a checksum for file or string integrity.

Search the web for "md5.c". Look for the implementation by L. Peter Deutsch. This implementation of MD5 is free, very solid, and easy to use. Get the accompanying md5.h file along with it.

You should find it all over the place -- it's used everywhere.

Actually, MD5 is one of the standardized hash functions used for fingerprinting of X.509 certificates (think SSL). It was invented as a cryptographic hash, not a file checksumming algorithm.
