pySSHA 0.6

Create and verify LDAP password and hash

# pySSHA-slapd
Python hashlib generator born as a script to test OpenLDAP user passwords.
It supports salted:

- md5
- sha1
- sha224
- sha256
- sha384
- sha512

Introduction
------------
pySSHA-slapd is a simple SSHA string encoder e checker that's quite easy to use:
````
python3 ssha.py -p slapdsecret
{SSHA}omu7YHgg6_uqOIN_epZtfJtGo0ruwdSr
````
Usage
````
usage: ssha.py [-h] -p P [-s S] [-salt_size SALT_SIZE] [-c C] [-enc ENC] [-b]
[-prefixed] [-d D]

Usage: python ssha.py -p Password[-c SSHA hash to check]

optional arguments:
-h, --help show this help message and exit
-p P Password to encode
-s S Salt, 4 bytes in hex format, example "fooo": -s
666f6f6f
-salt_size SALT_SIZE salt lenght
-c C {SSHA} hash to check
-enc ENC Encoder to use, example: sha1 sha224 sha256 sha384
sha512
-b if {SSHA} hash is in base64 format
-prefixed if suffixed or prefixed salt
-d D Debug level from 1 to 5

Dependencies
------------
Python3 and hashlib

Usage examples
--------------

You can adopt a specified salt for hashing, in hex format:
````
python3 ssha.py -p slapdsecret -s 74be2629
{SSHA}w5CJCwNQk44NjTYzcMZNKbE6Bu90viYp
````

Verify if a password is valid comparing it with a SSHA hash:
````
python3 ssha.py -c {SHA1}w5CJCwNQk44NjTYzcMZNKbE6Bu90viYp -p slapdsecret
````

Same as previous but ssha hash is in base64 format (like ldapsearch output):
````
python3 ssha.py -c e1NIQTF9dzVDSkN3TlFrNDROalRZemNNWk5LYkU2QnU5MHZpWXA= -b -p slapdsecret
````

Same as the previous but with maximum debug level
````
python3 ssha.py -c e1NIQTF9dzVDSkN3TlFrNDROalRZemNNWk5LYkU2QnU5MHZpWXA= -b -p slapdsecret -d 3
