<h2 id="DESCRIPTION">DESCRIPTION</h2>
<p><strong>hash_password</strong> calculates the hash of a supplied password using bcrypt.</p>
<p><code>hash_password</code> takes a password as an parameter either on the command line
or the <code>STDIN</code> if not supplied.</p>
<p>It accepts an YAML file which can be used to specify parameters like the
number of rounds for bcrypt and password_config section having the pepper
value used for the hashing. By default <code>bcrypt_rounds</code> is set to <strong>12</strong>.</p>
<p>The hashed password is written on the <code>STDOUT</code>.</p>
<h2 id="FILES">FILES</h2>
<p>A sample YAML file accepted by <code>hash_password</code> is described below:</p>
<p>bcrypt_rounds: 17
password_config:
pepper: "random hashing pepper"</p>
<h2 id="OPTIONS">OPTIONS</h2>
<dl>
<dt>
<code>-p</code>, <code>--password</code>
</dt>
<dd>Read the password form the command line if [password] is supplied, or from <code>STDIN</code>.
If not, prompt the user and read the password from the tty prompt.
It is not recommended to type the password on the command line
directly. Use the STDIN instead.</dd>
<dt>
<code>-c</code>, <code>--config</code>
</dt>
<dd>Read the supplied YAML <var>file</var> containing the options <code>bcrypt_rounds</code>
and the <code>password_config</code> section containing the <code>pepper</code> value.</dd>
</dl>
<h2 id="EXAMPLES">EXAMPLES</h2>
<p>Hash from the command line:</p>
<pre><code>$ hash_password -p "p@ssw0rd"
$2b$12$VJNqWQYfsWTEwcELfoSi4Oa8eA17movHqqi8.X8fWFpum7SxZ9MFe
</code></pre>
<p>Hash from the stdin:</p>
<pre><code>$ cat password_file | hash_password
Password:
Confirm password:
$2b$12$AszlvfmJl2esnyhmn8m/kuR2tdXgROWtWxnX.rcuAbM8ErLoUhybG

Confirm password:
$2b$12$AszlvfmJl2esnyhmn8m/kuR2tdXgROWtWxnX.rcuAbM8ErLoUhybG
