Creating and communicating passwords
====================================

Users are unreliable.  They forget passwords.

Processes sometimes suck and require you to set passwords.  It's a worst-practice and yet it's a common one.  The least we can do is stop pretending it doesn't happen and give you some tools to handle it.


Create UNIX password hash
-------------------------

I use a simple script I call *hashit.sh*.

Similar code is all over the Internet, but the orignal source seems to be the ActiveState official website.

.. code-block:: bash
	:linenos:

	python -c "import getpass, sys, random, string, crypt;
	randomsalt = ''.join(random.sample(string.ascii_letters,8));
	sys.stdout.write(crypt.crypt(getpass.getpass(), '\$6\$%s\$' % randomsalt))"


Store or communicate a password reliably
----------------------------------------

Given font differences and difficulty hearing things clearly by phone, phonetics are definitely the way to go for password storage and communication.

:download:`Download ddpwprint.py <code_samples/ddpwprint.py>`

.. literalinclude:: code_samples/ddpwprint.py
	:linenos:
	:language: python

You can read the output clearly to most government and military officials.
