Just learning hashcat.

[Hank B]

Total neophyte here. I've been trying different things with this amazing program.
I have one old forgotten password of mine I'm trying to recover.
I  found the hash (MD5?) and I entered this command:
hashcat  -a3 -m22500 myhash.txt -o cracked.txt
It seems to be incrementing candidate length automatically with no end in sight.
Is that correct?
Thanks

well plain md5 is mode m0 not m22500 (MultiBit Classic .key (MD5))

look at the used charset or guessbase? in the status window, due to the fact, that you didnt provide a mask for attacking, hashcat uses a built in standard mask and increment this mask, this is okay for fast test or anything else, but will never perform a "full" bruteforce

anyway,, if you have any clue about your old password a specialized mask attack or dictionary attack would be more suitable
