encrypt / decrypt with MD5

[krawat]

I'm looking for an example to encrypt / decrypt a string with MD5 hash .

Has anyone experience in such a work

Thanks for any answer !

Ya can't decrypt MD5 string.... example... ya have 700 characters... ya can still put it thru md5() and still get 32 character answer... so that's inpossible... ya should check mcrypt instead.

In my opinion it is impossible. As far as i know, MD5 is one-way cypher, it can't be decrypted, just brute force could be used.

even you do brute force, you can\'t bring back the original text, because md5 is a hashing technique, the md5 produces values computed by the hash math algorithm... its one way... MD5 is not an encryption, it maybe considered as the signature or verification key... against the original text to make sure that no changes has been made on the text/message.
