hashmode sha1(sha1($pass).$salt) support? - NocFlame - 05-04-2020
I recently needed support for what could be called hashmode 4510 - sha1(sha1($pass).$salt) but this seems to be missing. Is this algorithm really missing or is it supported in some other way that i have missed?
Could not find any information from GitHub about this specific issue either.

This seems to be similar to:
-m 4520 = sha1($salt.sha1($pass))
-m 4521 = Redmine
-m 4522 = PunBB
but with the $salt at the end instead of at the beginning (all of the above use the salt at the start).
Yeah, I don't think it's currently supported and it could make sense to request it on github.
... but don't forget to follow this rules: https://hashcat.net/wiki/doku.php?id=frequently_asked_questions#i_want_to_request_some_new_algorithms_or_features_how_can_i_accomplish_this
We need some motivation why to add this, where this algorithm is being used, are there any limitations (salt length , pass length), provide some examples with passwords etc
