Hey there, I'm currently working on converting an ASP.NET, C# site/application to PHP, and I've run into a small snag. The login algorithm hashes the user passwords like so: MD5 md1 = new MD5CryptoServiceProvider(); byte[] buffer1 = new ASCIIEncoding().GetBytes(stringToHash); byte[] buffer2 = md1.ComputeHash(buffer1); md1.Clear(); return Convert.ToBase64String(buffer2); The challenge here is that in this conversion, I'm also migrating the users over to a different system which uses a completely different hashing mechanism. So, really, I need to be able to un-hash these values, if that's even possible. Thoughts? Options? I'm afraid this is one way hash, that I'm not going to be able to do anything about, unfortunately.
