Please test. Here's what I am getting with it, vs. 1.7.9's incremental mode with the same CHARSET_* settings and the same training and test sets. For my testing, I ran "shuf" on the full RockYou list (32.6M passwords). Then I split the resulting shuffled list in two: exactly 1M for test set, and the rest (about 31.6M) for training set. There's no overlap between the two, but some of the passwords that occurred in the original RockYou list more than once also occur in both sets. This simulates what happens with common passwords across two different yet similar sites, where cracked (or otherwise known) passwords from one are then used to attack hashes from the other. $ shuf r > rs1 $ head -1000000 rs1 > rs1a $ tail +1000001 rs1 > rs1b $ wc -l rs1? 1000000 rs1a 31603388 rs1b 32603388 total $ sed 's/^/:/' < rs1b > john.pot $ perl -ne 'chomp; print "dummy:", "\$dummy\$", unpack("H*", $_), "\n";' < rs1a > pw1 #define CHARSET_MIN 0x01 #define CHARSET_MAX 0xff #define CHARSET_LENGTH 24 JtR 1.7.9 took almost 4 minutes to generate a .chr file with these settings from the .pot file above. The new version with the patch I posted takes under 50 seconds to do the same (indeed, the .chr file is different - it's for the new version, too). This is on Xeon E5420 (using one core).
