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
