SimpleHash class support? - scriptx - 11-02-2011 10:43 PM

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!

I didn't know of any projects off hand, apart from our own proprietary system, so I googled for bits and pieces of the source code. As it turns out, this particular method dates back 10+ years, with examples for vb6 and all current .NET languages. It might be hard to identify from closed-source projects, but it's certainly been used by many windows developers.

It seems some DNN developers have used this method as well for securing their own databases.

I retract my request!.. I was able to extract and convert the data I needed for an effective hashcat file Smile
