How can find a sha256 hash start with ***** with hashcat & markprocessor? - kangduwang - 12-26-2019
Instead of find a full hash, is there anyway for hashcat to find a bunch of hash start with a given prefix & print it to a file? How may i do that?

have a look at -m 5100 = Half MD5 which does more or less exactly what you describe (just for MD5 instead of sha256)... the problem with too small prefixes is that there will be too many results/collissions and hashcat won't be able to print all of them (see https://github.com/hashcat/hashcat/blob/4d286d5dc7a3b8b8602ea893a5f6da8a4b757ac3/docs/limits.txt#L37-L41)

Is there any option?
