NAME:
   rPasswd - A small and secure password generator and encryptor tool

USAGE:
   rpasswd [global options] command [command options] rpasswd [global options] <length>

   Example: rpasswd --symbols 20 --uppercase 32

DESCRIPTION:
   CLI tool to generate secure passwords as described by AgileBits 1Password[1]. With support for password encryption as well using bcrypt, scrypt, argon2 or pbkdf2.

    [1] https://discussions.agilebits.com/discussion/23842/how-random-are-the-generated-passwords

COMMANDS:
   gen, g    Generate a random password including lower-upper cases, digits and symbols characters by default
   cgen, cg  Generate a custom random password with specified lower-upper cases, digits and symbols characters
   enc       Encrypt a given password using a hashing function (bcrypt, scrypt) or a key derivation function hash (argon2, pbkdf2)
   help, h   Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --version, -v  shows the current version (default: false)
   --help, -h     show help (default: false)
