See https://github.com/hashcat/hashcat/issues/1488#issuecomment-356641298

We need real samples for longer passwords before we can implement this.

I added some real samples to https://github.com/hashcat/hashcat/issues/1488#issuecomment-356754100

As @jsteube found out: One simply needs to pad with zero bytes to a next segment of 16 bytes.

@jfoug how do we make that change to dynamic_20?

kholia commented 6 years ago

Do we need a new dynamic format to handle these longer password lengths? Or can the existing format be extended to handle both types of password lengths and hashes?

magnumripper commented 6 years ago

The existing format should be extended. Trivial fix in a normal format but I'm not sure how to do it in dynamic.
