There are a couple of problems with this: 1. cmp_all() is not always called. When the number of hashes for a salt is above a threshold, a get_hash*() function is called instead. 2. cmp_all() may be called multiple times if there's more than one hash for a salt, but the threshold mentioned above is not reached. > If there were no set_salt or set_key calls between last cmp_all call > then don't do hash calculations inside cmp_all - just in case. Yes, this addresses #2 above. #1 may be addressed by introducing a new FMT_* flag as I pointed out in another message, but this is a tradeoff. Alexander
