File-based custom charsets

[thorsheim]

Setting up custom charsets using -1 ABCDEF... works nice as long as you stick to the built-in charsets (http://hashcat.net/wiki/mask_attack), but if you want to go beyond that you'll have to put them on the command list after -1.

Attempting to attack CP437/CP850 charsets (see http://tbhost.eu/charset.txt, charsets used for Freerainbowtables), you're in for trouble because the command line (both Windows & Linux) will interpret certain characters as options or shell commands.

Expanding the list of built-in charsets could partially solve this, but since I'd like to test partial/full UTF-8/16 charsets, the command line with built-in charsets doesn't get flexible enough.

So my suggestion is to allow for putting custom charsets in textfiles.

(I'll openly admit that I rip of Bitweasils Multiforcer here, where he does exactly that with either single charset input (--charsetfile) or per-position charset file (--charsetfilemulti)

Thanks for suggestion. Since I knew you would request this before I already added this to latest beta version. Please check it.

You can now use "-1 charsets/cp437-850.charset" instead of doing "-1 ?l?d?s?u". If the value after -1 exists as a file, it will load its content. Otherwise it will interpret it as a custom charset buffer like before.

The mask itself does not change, so you can still use ?1?1?1?1?1?1?1 which enables the per-position functionality.

Excellent, thx atom!

First test:

oclHashcat-plus64.exe -m 3000 -a 3 -o LM-found --outfile-format=6 LM-input -1 charsets\lm-cp437-850.charset ?1?1?1?1?1?1?1 -n 80 --gpu-loops 1024
** Valid keyfile for beta usage: XXXXXXXX (XXXXXXXXX)
