Running hashcat on multiple hash files - slawson - 10-23-2019

Is there a way to do this?  I tried this:

hashcat -m 16800 --show *.16800

This actually runs, but it only shows results for the first file in the directory.

Have you tried to cat them all in one file?


RE: Running hashcat on multiple hash files - slawson - 10-23-2019

I did the Windows equivalent

copy /b *.16800 all.16800

That works, but I guess I was just curious if hashcat can handle multiple files at once.

hashcat currently expects the target hash to be a single file (or a single hash on the command line).

Pay attention,
/B          Indicates a binary file

While 16800 mode is text only.

Under the Windows command line, the /b switch to copy preserves all original content when concatenating files. In this context, it is the correct switch to use.

I hate to necro-thread, but don't want to start a new thread to follow up.... There doesn't seem to be much of a speed advantage for cracking multiple MD5crypt hashes in one file, rather than doing them independently. Always thought the calculation of the hash from the candidate is the rate limiting step, not comparing the hashes to those in the given file. 
Is this expected behavior?

Agreed - I think the OP was motivated by convenience, not efficiency. Big Grin
