pack2

pack2 is meant to be a replacement for iphelix's PACK. This is a work in progress. Not all features are available and while being similiar some will differ slightly.

note

It's in a totally unfinished state but I wanted to have it public before CMIYC 2020

requirements

You need to have Rust installed. The recommended way to do so is using rustup.

building

$ cargo build --release

Your binary will be located at target/release/pack2
To squeeze out more optimizations we use some compiler flags in the release profile.
This results in a longer compile time in favor of running a bit faster.

design principles

Unless stated otherwise all tools adhere the following rules:

• If no input file is specified it reads from stdin
• If no output file is specified it writes to stdout
• Infos (e.g. stats) are always written to stderr
• Input lines in the $HEX[] format are always decoded before any further processing
• If at least one character of an output line is outside of \x20 - \x7e it will be encoded in the $HEX[] format

usage

filtermask

Note: This will fail horribly in many cases. See #6 for more details.
Filters the input by a given mask, only writing the lines that match the mask.

$ cat input.txt
test
foobar
Password

$ pack2 filtermask ?l?l?l?l input.txt
test

rulegen

There were plans to integrate this as well but since rulesfinder (also written in Rust) got released there's really no point reinventing the wheel.

statsgen

Generates statistics of a given wordlist.

$ pack2 statsgen < input.txt
[+] Analyzed 3 / 3 passwords.
[*] Length distribution: (min: 4 max: 8)
[+]                          4: 33.33% (1)
[+]                          6: 33.33% (1)
[+]                          8: 33.33% (1)

[*] Charset distribution:                    count   min   max
[+]                 loweralpha: 66.67%           2     4     6
[+]                 mixedalpha: 33.33%           1     8     8

[*] Simple masks distribution:               count   min   max
[+]                     string: 100.00%          3     4     8

[*] Masks (top 25):
[+]                   ?l?l?l?l: 33.33% (1)
[+]           ?u?l?l?l?l?l?l?l: 33.33% (1)
[+]               ?l?l?l?l?l?l: 33.33% (1)
?l?l?l?l	33.3333	1
?u?l?l?l?l?l?l?l	33.3333	1
?l?l?l?l?l?l	33.3333	1

You can also provide the -o flag to specify the output file. Type pack2 help statsgen to see all options.

unhex

Decodes and writes lines using the $HEX[] format. Lines not using said format are unaffected and written as is.

$ echo '$HEX[52c3b67363687469]' | pack2 unhex
