`hash_password` now actually accepts password from stdin. The `getpass` reads from TTY, and does NOT accept stdin in any way. The manpage has been updated to reflect that.

<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>

<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>
