Subject: Cracking ODF files with JtR


I have committed a patch (to magnum-jumbo repository) to crack pre-1.2
ODF documents (OpenOffice / LibreOffice files) with JtR.


1. run on pre-1.2 ODF files (which use Blowfish encryption).
2. Run JtR on output of

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).
