SimpleHash class support?

[scriptx]

I've come across a few instances where developers include and invoke the below SimpleHash class into a project, using this as a one way encryption for passphrases.

The original MD5 (or respective SHA) algorithm used gets pretty mangled when the salt is re-added, making isolating the original MD5 impossible.

Any chance for some kind of support, or any ideas from the community on how to test hashes computed using this class?

Thanks in advance everybody!
