I think it would be wise to include the below change before releasing it: The current mscash2 format (dcc2) use the same tagging (eg. in john.pot) as the older mscash format (dcc1). I think this is a bad thing. Furthermore, I believe the iteration count can be altered but it's currently not stored with the hash but hard-coded (with a #define) in mscash2_fmt.c. - I propose we keep the old format for mscash (dcc1): M$test1#64cd29e36a8431a2b111378564a10631 - I propose we use this new tag + iteration count for mscash2 (dcc2): $DCC2$10240#test1#607bbe89611e37446e736f7856515bf8 We will probably be able to attack different iteration counts in the same run. Anyone agreeing or disagreeing on this? magnum
