Subject: Cracking KeePass 1.x files with JtR

Hi,

I have committed a patch (to magnum-jumbo repository) to crack KeePass
1.x files with JtR.

Usage:

0. gcc keepass2john.c -o keepass2john # this step will be integrated
in john and won't be needed later
1. run keepass2john on KeePass 1.x files.
2. Run JtR on output of keepass2john

Performance on AMD X3 720 CPU,

$ ../run/john -format=keepass -t
Benchmarking: KeePass SHA-256 AES [32/64]... DONE
Raw:	38.6 c/s real, 38.6 c/s virtual

ODF format uses 50,000 iterations (default value) of AES encryption of
a 32-byte value. It is another candidate for GPU implementation.
KeePass 2.x support is currently TODO (patches are welcome).
