Need secure one-way string encryption? Try the Hash() function which takes a string and returns a 32 byte hexadecimal string, converted using an algorithm called MD5. You’ll not be able to decode the string, but you’ll be able to compare it to other encoded copies (which makes it useful for safely sending data back and forth between clients and servers). (Applies to: ColdFusion 4.5.1 (or later))
