## SYNOPSIS
|
||
|
|
|
||
|
|
`hash_password` [`-p`|`--password` [password]] [`-c`|`--config` <file>]
|

|
|
|
||
|
|
## DESCRIPTION
|
||
|
|
|
||
|
|
**hash_password** calculates the hash of a supplied password using bcrypt.
|
||
|
|
|
||
|
|
`hash_password` takes a password as an parameter either on the command line
|
||
|
|
or the `STDIN` if not supplied.
|
||
|
|
|
||
|
|
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 `bcrypt_rounds` is set to **10**.
|
||
|
|
|
||
|
|
The hashed password is written on the `STDOUT`.
|
||
|
|
|
||
|
|
## FILES
|
||
|
|
|
||
|
|
A sample YAML file accepted by `hash_password` is described below:
|
||
|
|
|
||
|
|
bcrypt_rounds: 17
|
||
|
|
password_config:
|
||
|
|
pepper: "random hashing pepper"
|
||
|
|
|
||
|
|
## OPTIONS
|
||
|
|
|
||
|
|
* `-p`, `--password`:
|
||
|
|
Read the password form the command line if [password] is supplied.
|
||
|
|
If not, prompt the user and read the password form the `STDIN`.
|
||
|
|
It is not recommended to type the password on the command line
|
