I just saw a blogpost linking to this optimized sha1 implementation: https://hashcat.net/p12/ Original blog post here (swedish): http://secworks.se/2013/01/nytt-satt-att-optimera-sha-1/ In short, the creator of hashcat analyzed sha1 and found out 21% of the xor-operation cancel out... This leads to the possibility to optimize the implementation. I guess the john code could also use this optimization. Regards, Albert Content of type "text/html" skipped
