Really useful python hash-identifier from blackploit.com allows you to identify types of hashes.
I made a web front for hash-identifier
🙂
EDIT: Kali linux now has hash-identifier built in.
This website no longer hosts an online version because of the host I use.

An online hash identifier has been created and can be found at http://dfcode.org/onlinehashidentifier.php
And doesn’t require any download.
