I don't remember for sure, but that sounds right.  pdfcrack uses brute
force, so it can be quite time consuming - as I mentioned before, I
usually do a run of digits only first, then one run with digits and
the characters present in the filename.  If the password is
alphanumeric, the decryption will take quite some time if the password
is over 4 chars long, so then it's a toss-up: go ahead and do one
last, long run with all chars or take a chance that it's alphanumeric.

At least you have a spare machine ;)

Good Luck!
