Question: I've tried using this MD5 encryter/decrypter: MD5 Decrypter.com, MD5 Decryption, Free MD5 Decryptor, Security, MD5 Hash, MD5 Security. to decipher certain MD5 hashes like 62f75a320a5b1a0c61879a57dac58352=test.klwn.com but I have not been able to crack this particular hash and it's keeping my CMS from seeing the correct domain in my tplconfig.php and my session.php files. Below is the "mystery" hash that keeps coming back "not found in the database"......
Mystery hash=6666cd76f96956469e7be39d750cc7d9

Basically, there is nothing called hash decryptor, simply because there is an infinite number of data that can generate a certain hash. The hash function is not used to generate encrypted information, but rather, to generate integrity verification information. For example, if I choose a very simple hash function that performs XOR between bytes, then, for the following data bytes:

00000000 00000000 00000000 00000000 00000001 00000000 00000000

the hash will be 00000001.

Note that the following data bytes will also have the same hash:

00001111 10001111 10000000 00001000 00001000 00000000 00000001

And also note that given the hash byte 00000001 you can never know whether the original information was the first or the second one, or even something else. You can only use the hash to verify the information integrity *when* you already have the original information.

What the site md5decrypter.com does is that it has a huge database of different data and their corresponding hash values. When you provide a hash, the database is searched for an entry containing the hash you provided, and if a match is found, the corresponding data is returned.

You must also know that you can never guarantee that the information returned by the web site is the information you are looking for. For example, if I tell you the hash of my web site name is 62f75a320a5b1a0c61879a57dac58352, then this does not imply that my web site is test.klwn.com, simply because there is an infinite number of site names that will have the same hash.
