I\'ve been looking for a Classic ASP script that allows me to hash a string using the MD5 algorithm. I need to match this hashed string against the same string in an ASP.NET
If you want exactly what .Net does , You can decompile ComputeHash method from HashAlgorithm class(also consider MD5CryptoServiceProvider class) from .Net assembly mscorlib.dll (from the path like this in your computer :C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\mscorlib.dll) and then convert the codes to ASP-Classic. Some good (free)Decompilers are:
