    Thread: Keepass file Line-length exception.
Post: RE: Keepass file Line-length exception.

You cannot directly load the keepass file itself - you need to extract the hash to provide to hashcat.  John the Ripper's keepass2john or harmj0y's Python port of keepass2john (https://gist.github.c...

To cross-check your methodology, consider creating a new KeePass volume with the same specifications and a known password, then try to crack that. :)

There isn't an option to try all methods, because -- by design -- it is difficult to confirm which algorithms were used (other than by successfully mounting it or cracking it). The best you'll be a...

Post: RE: PeopleSoft with salt

The salt is intrinsic to the hash. The only way to rework the salts would be if you already had the plain text password.

I'm not clear from your post which tests are the ones that are for a large number of hashes. And to clarify, by "Optimized" do you mean that you are using the -O flag?

It's possible that the password was added by some tool other than Acrobat. It sounds like you found a workaround with using qpdf?
