# splitlen-extra by _NSAKEY
# Based on the concept of splitlen from hashcat-utils which can be found here:
# https://hashcat.net/wiki/doku.php?id=hashcat_utils
# As of version 1.0, splitlen allow up to 64 char passes, and this script
# takes orders of magnitude longer to run. Consider this script obsolete.

# Usage: ./splitlen.sh wordlist.dict dictionary-folder
# $1 is the name of your dictionary and $2 is the name of the folder for the
# output.

# BEGIN EXTENSIVE DOCUMENTATION

# The script just extracts every line that meets a certain length from the
# word list and dumps it in the appropriate file.  The rationale for doing
# all of this in the first place can be found here:
# http://hashcat.net/wiki/doku.php?id=oclhashcat#dictionary_loading

# I dislike the fact that splitlen truncates all > 15 character passes but
# also understand why the hashcat team made that design decision. The
# original version used cat instead of strings, but the script kept dying
# until I started using strings. It probably kept dying due to some bug
# with an unusual charset, but I figure if someone's smart enough to use
# hex in their passes, they deserve a break.

# The script is dumb for 2 reasons (Aside from not being particularly clever):
# 1. It assumes that the folder specified in $2 already exists.
# 2. If your dictionary file's longest word is under 50 characters, you will
# end up with a bunch of 0 byte files for the upper ranges. Just include
# everything from hashes.org in your giant dictionary and you won't have to
# deal with this edge case.
