How to determine hash encoding

([msg=88609]see How to determine hash encoding[/msg])

Hi all,

This is my first post on these forums so i apologize in advance if I'm posting in the wrong area.

Anyway I was wondering how you determine what type of hash encoding is being used if you say find a password that is encrypted for example:

7e456abc3b7e4fc96bae0482e34bbbb8

Any help would be greatly appreciated

Thanks!

Usually I'd reference something like this to see which length matches. In this case, it's 128-bit, so it's likely one of: MD2, MD4, MD5, RIPEMD, RIPEMD-128, Snefru.

Once I've narrowed it down, I'd see if there's anything in a file or something else that may key me in to its type; if nothing else, consider the age of the source - what was the most popular hashing type when it was made?

Thanks for the link that was really helpful as was thinking in relation to the age of the source good thinking :)
