[MD5 Reverse Lookup]
http://www.md5lookup.com
There’s no way to reverse the process of a hash algorithm, i.e. you can find lots of pairs of integers that make a sum of 16. However once we encountered a hashed sum which is so important that we must know what made this sum, the only way to solve is to brutusly guess. The time required to retreive a correct answer depends on, mostly, your luck. But thanks god and the so generous people who created their databases for others to query for a text. This site is a pretty good one, and I will never tell you that it can be used to search for MD5-hashed passwords in many SQL tables.
