MD5 Help - wormblack - 10-21-2019
what sort of attack would i use on an md5 hash if i only know that it is a 32 character long hex string?

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.

yes the plaintext is a 32 char hex string.
Is this something i should just forget about even trying or is there any sort of route i could take?

Just forget about even trying is a good strategy if you only have a hash and know the plaintext is 16^32 (340282366920938463463374607431768211456) possibilities.
