md5 with two different salts - tonyvg - 11-27-2021

How to perform
Quote:md5($salt1.$pass.$salt2)
on hashcat?

Now I use JTR with dynamic to do this, but it can only use CPU and really slow.

This exact mode isn't in hashcat at the moment, you can use -m 10/20 with rules for prepending/appending one of the salt as a workaround.

But what I am facing is multi hashes with different salt1 and salt2, so I cannot use rule to append.
Sad

You can, it's just not gonna be that efficient (the more salts you have).
If you have some coding skills you can try to add that algo to hashcat yourself, or you can open an issue on github to request it.
