Question

MD5 hash function for VB6

Asked by: Frosty555

So far I've found activex controls and VB.NET stuff about writing md5 hashes, but no native VB code that does it, and the md5 hashing algorithm is too complex for me to replicate.

Can somebody please show me how to write an MD5 hash in native VB6 only? WinAPI calls are fine, I just don't want activex/external dlls I have to download and distribute. I'm trying to write a function in native VB6 that does a standard MD5 hash of a string, the same kind of hash that is performed by PHP's md5() function.

It doesn't need to be terribly optimized. These activex controls are all because these people expect you to try and hash every file on your entire hard drive, I'm just doing a one-time password hash. Nobody will care if they have to wait 0.0025 seconds as opposed to 0.0001 seconds.

I do have source code in for a C DLL that I have used many times calling from a VB6 program.  

If you decide you will go with an external DLL, let me know and I can get the link for the Source for the C DLL that I use.....
