Hi there,

Most likely, you can't. Hashing is a one-way process where a lot of data is hashed into a unique key. You could hash a short password or an entire DVD full of information, and you would get a hash key with the same size. If the process was reversible, you would have invented the best compression scheme.... ;)

That said, I read that there are "rainbow tables" that contain lists with many original values for MD5 hashes: http://en.wikipedia.org/wiki/MD5

Cheers,

Imar
