    MD5 is a hashing algorithm, not an encryption algorithm. There is more
    than one input for this algorithm which will generate the same
    hash, as
    opposed to a cipher.

Go to: http://md5decryption.com <http://md5decryption.com/>
In "Please input the MD5 hash that you would like to be decrypted:" field, put: 7db4a8dae498d1b4686ebd1f79326602
See the result in "Decrypted Text:" field.
Please read what they write on their web page (stresses by me):

=== quote begin ===

Encrypt MD5 hash, Decrypt MD5 hash
MD5Decryption.com allows you to enter a MD5 hash and we will look *into our database*
and try to decrypt MD5. Basically it is a MD5 decrypter.

What is an MD5 hash, or MD5 Checksum?
MD5 is a 128-bit message digest function.
It is used commonly in user authentication and MD5 checksum for data integrity.

How many MD5 hashes are in our database?
*We have encrypted* more than 105,300,000 words, phrases, acronyms, etc since 2006.

=== quote end ===

So they have build themselves a database of a limited number of md5 hashes and use that to resolve your requests. MD5 is a one way hashing function. Full stop. Don't believe it? Well... I generated a hash of "wrxlbrmpf" which is d162435be814d6c6f4e1e4f077e5343d. This hash is not found in their database. Or better yet: Hash a 1GB movie and ask them to decrypt that. It would definitely be awesome if you could store a 1GB movie inside a 16-Byte hash...

Sven
