@rico is right - you've got a stray hyphen (or if your filename actually begins with a dash, you'll need to rename it) And I'm sorry to be the bearer of sad news, but your other question is right -...

More cores is good. Current state of the art is NVIDIA (because of the LOPT3.LUT instruction set, I think?)

It is definitely supported by hashcat. Some benchmarks from @epixoip are here: https://gist.github.com/epixoip/973da7352f4cc005746c627527e4d073

For future searchers, note that SLI is not necessary for hashcat - and adds overhead that actually impacts performance. Instead, allow hashcat to handle the multiple GPUs directly. https://hashcat....

PCI-E lanes are good for gaming, but hashcat does not care. x1 would even be sufficient for hashcat. If you intend to use the system for multiple password-auditing purposes, a minimum of x4 might ...

    Thread: Problems with CRC32
Post: RE: Problems with CRC32

hashcat's crc32 implementation expects a second field.  From the example hashes (https://hashcat.net/wiki/doku.php?id=example_hashes): 5. You can consider the second part as a “salt”. If it is ...

It sounds like you're doing a lot of work to create word lists with a lot of permutations up front, and storing them. But hashcat has features that make this less necessary. In brute force attacks,...
