alexb, to clarify: you've told hashcat that you want to use your own wordlist (-a 0), but you haven't supplied one.

You could use mp64 to generate them, maybe? https://hashcat.net/wiki/doku.php?id=rules_with_maskprocessor Might still have to dedupe it a little after, depending

Post: RE: combine rules without duplicates?

Dedupe of text on the command line is a largely solved problem. Depends on your platform. 'sort -u' on Unix-likes covers most use cases. On Windows, 'sort.exe /unique' seems roughly equivalent.

There's also this project, that tries to detect rules with redundant results: https://github.com/0xbsec/duprule/

It sounds like you've discovered a number of options from your research. What are they? What criteria have you considered for prioritizing them?

I don't know of a way to do this with hashcat today. But the "jumbo" edition of John the Ripper has a "hidden" option (--keep-guessing) that will do this. For CRC32, the source file has to be asse...

When using masks, hashcat uses the same sequence of passwords every time. I haven't read your script thoroughly, but how does the script teach hashcat that it shouldn't just stop at the first one it ...

It's C. Try compiling it on a Linux system.

Huh - yeah, I went back through my notes/scripts and all the iconv items were just -f [source-format] -t [dest-format]. I thought it was harder than that, but I guess not!

Could be a power issue. Have you audited real-world power draw from the wall for each PSU under various workloads? How is the power balanced across the board and GPUs?

Hmm - that seems like enough headroom to me, on each power supply. With ~180W max per 1080 that's only 540W plus 460W for your mainboard, which seems like plenty. Only other thing I can think of: I...
