Gen - Random Password/Wordlist Generator
------------------------------------------------------------------------

SUMMARY

DETAILS

Gen is a small password/wordlist generator written in Perl. The generator
can be used as the input for many types of purposes, from administration
security tasks to brute force tools utility.

Tool:
#!/usr/bin/perl
#
# gen.pl Password generator by nuTshell
# <carloslack at gmail dot com>
# http://nutshell.gotfault.net
#
# Part of eland(c) by posidron http://posidron.gotfault.net
#
# Gen was originally written to be part of Eland and then i`ve
# decided to publish this "user" version.
#
# Usage eg:
# $ ./gen.pl -all 8 3 join users.txt
# [!] Generating: Ge|{R[12
# [!] Generating: ;?#MMT%A
# [!] Generating: k8bW$RHx
#
# Passwords number: 3
# Passwords length: 8
# Output file pass_all.txt created
# Combo file combo.txt created
# $ cat users.txt
# root
# admin
# you
# $ cat combo.txt
# root:Ge|{R[12
# root:;?#MMT%A
# root:k8bW$RHx
# admin:Ge|{R[12
# admin:;?#MMT%A
# admin:k8bW$RHx
# you:Ge|{R[12
# you:;?#MMT%A
# you:k8bW$RHx
