@jmgosney What password length(s) does @hashcat benchmark mode use for sha256crypt, md5crypt, phpass? In particular, in benchmark results at https://gist.github.com/epixoip/973da7352f4cc005746c627527e4d073 … and https://gist.github.com/epixoip/ace60d09981be09544fdd35005051505 …. I'm also interested in these for atom's 1080s at 90W (energy-efficient mode). Thanks!

"--markov-disable" made very little difference (maybe 181 to 182 kH/s). No such discrepancy between benchmark and cracking is seen for sha512crypt (hashcat mode 1800), so our previous comparison looks valid. I'm glad I tested hashcat's sha256crypt myself before posting a new one.

The benchmark mode is fine. It's just using a salt of length 8 while the example hash uses the length 16. If you truncate the salt to 8 in non-benchmark mode you should see the same performance.

Confirmed. Getting 288 kH/s cracking a salt length 8 sha256crypt hash with mask length 7. Will use these lengths for our FPGA benchmarks.

This same hash, running a GTX1080 and capped at 90W, is doing 355kH/s
