Subject: Add support for cracking M$ Outlook's PST files


The attached patch (against magnum-jumbo branch) adds support for
cracking M$ Outlook's PST files. In my experience, CRC32 (custom
version) collisions can be generated in less than 15 minutes on AMD X3
720 CPU (1 core).

$ ../run/john -fo:pst -t
Benchmarking: PST custom CRC32 [32/64]... DONE
Raw:	23601K c/s real, 23840K c/s virtual

There is one warning in the code "pst-crc32.h:554:25: warning: cast
from pointer to integer of different size" which needs fixing. magnum,
Can you take a look?


1. Compile and run "pst2john" on pst files. Currently this tool is
available from For integration
into john, this codebase needs to be heavily trimmed.
2. Run john on output of pst2john.

I will send a mail to john-users once tha patch is ready for general
usage. Comments / Feedback is welcome!
