Subject: sunmd5 round count fixed to 500? [patch]
I've just noticed that the sunmd5 (sunmd5_fmt_plug.c) plugin has the rounds=904 hard coded, and won't load hashes with rounds=0 (so just 4096) or with other number of rounds. Guess it was somehow forgotten like that ... the fantastic "patch" below allows hashes like the following ones to be processed just fine:
$md5,rounds=1000$cd/IPUR.$$cK9VFbjyCVafobmZ11.qD1
$md5,rounds=904$ZVM0Ra/u$$5Shz0OCYcP2SSj4ltgYn./
$md5$6GiSSeL0$$F6rRJpg4Ee2hPN9kSFkoN0
$md5$eY5jk40I$$j3T35bMT4Alrk8rMCFBmE.
Cheers,
Costin
