MD5 Help wormblack Junior Member Posts: 15 Threads: 4 Joined: Oct 2019 10-21-2019, 06:00 AM what sort of attack would i use on an md5 hash if i only know that it is a 32 character long hex string?  royce Moderator à la mode Posts: 749 Threads: 4 Joined: Jan 2015 10-21-2019, 06:20 AM Do you mean that the plaintext is 32 characters? If so, then unless you have a strong idea of its composition, bruteforce cannot reach even half of that keyspace. ~ wormblack Junior Member Posts: 15 Threads: 4 Joined: Oct 2019 10-21-2019, 06:26 AM (10-21-2019, 06:20 AM)royce Wrote: Do you mean that the plaintext is 32 characters?

Is this something i should just forget about even trying or is there any sort of route i could take?
