Hi , I used a method CryptoFns.MD5HashUTF16ToString(string pValue) to encrypt passwords. Now I want to be able to decrypt the passwords. I tried using IdeaBlade.Util.CryptoFns.SimpleDESDecrypt(string pValue,string pEncryptionKey) but I don’t quite understand what the second string parameter should be.

You cannot decrypt a MD5 Hash. A hash is one way function.

If in your table, the users password is stored as a md5 hash, then when they try to login, you hash the entered password and compare it against the stored hash.
