I have been learning how rules modify password candidates in hashcat and have found using --stdout to a text file very useful.
I have noticed a significant difference in speed between hashcat-cli64.exe V2.0 and hashcat64 v5.1.0. but not in the way I expected.
For speed testing purposes I used a 118MB rule file and a single password candidate to modify.
A sample (not all) of the batch commands I used.
hashcat-cli64.exe V2.0
hashcat-cli64.exe -r TestRules.rule TestPass.txt --stdout >> TestOutput.txt
hashcat-cli64.exe -n 64 -r TestRules.rule TestPass.txt --stdout >> TestOutput.txt
hashcat64 v5.1.0
hashcat64 -r TestRules.rule TestPass.txt --stdout >> TestOutput.txt
hashcat64 -D 1 -r TestRules.rule TestPass.txt --stdout >> TestOutput.txt
hashcat64 -w 3 -r TestRules.rule TestPass.txt --stdout >> TestOutput.txt
I tried combinations of -w (hashcat64 v5.1.0.) and -n (hashcat-cli64.exe V2.0), or none at all, in my batch scripts with little to no effect.
Every time both output files were almost identical except for 10 - 20 lines out of approx 18921740 lines so the output is not significantly different which would have otherwise explained it.
The speed difference is huge:
hashcat-cli64.exe V2.0 - generally takes approx 70 seconds
hashcat64 v5.1.0 - generally takes approx 420 seconds
My system:
No GPU hashcat would be interested in so I use CPU option.
Win7 64bit Sp1 and all updates.
Could someone please let me know if I am using the wrong commands or if hashcat64 v5.1.0 is supposed to take longer for some technical reason, perhaps better validity checking etc?
Thank you
