Subject: Cracking ODF files with JtR
Hi,
I have committed a patch (to magnum-jumbo repository) to crack pre-1.2
ODF documents (OpenOffice / LibreOffice files) with JtR.
Usage:
1. run odf2john.py on pre-1.2 ODF files (which use Blowfish encryption).
2. Run JtR on output of odf2john.py.
Performance on i3-2120 CPU,
$ ../run/john -format=odf -t
Benchmarking: ODF [32/64]... DONE
Raw: 1316 c/s real, 1316 c/s virtual
ODF format uses PBKDF2 with 1024 iterations, hence it is another
candidate for GPU implementation. AES support is currently TODO
(patches are welcome).
Note: magnum-jumbo repository can be cloned from
