NAME

       synapse_hash_password  -  Calculate  the  hash of a new password, so that passwords can be
       reset

SYNOPSIS

       synapse_hash_password [-p|--password [password]] [-c|--config file]

DESCRIPTION

       synapse_hash_password calculates the hash of a supplied password using bcrypt.

       synapse_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 synapse_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 directly. Use the STDIN instead.

              Read   the  supplied  YAML  file  containing  the  options  bcrypt_rounds  and  the
              password_config section containing the pepper value.

       Hash from the command line:

           $ synapse_hash_password -p "p@ssw0rd"
           $2b$12$VJNqWQYfsWTEwcELfoSi4Oa8eA17movHqqi8.X8fWFpum7SxZ9MFe

       Hash from the STDIN:

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

       Using a config file:

           $ synapse_hash_password -c config.yml
           Password:
           Confirm password:
           $2b$12$CwI.wBNr.w3kmiUlV3T5s.GT2wH7uebDCovDrCOh18dFedlANK99O
