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 12.
The hashed password is written on the STDOUT.
A sample YAML file accepted by hash_password is described below:
bcrypt_rounds: 17 + password_config: + pepper: "random hashing pepper"
+ +-p, --password
+STDIN.
+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.-c, --config
+bcrypt_rounds
+and the password_config section containing the pepper value.Hash from the command line:
+ +$ hash_password -p "p@ssw0rd"
