Usage

$ wcbjs
wcbjs <command> [options]

Commands:
  wcbjs key                                 Generate symmetric key

                                            ad from STDIN.
  wcbjs derive-key <private_key> [public_k  Derive symmetric key from private an
  ey]                                       d public key.
  wcbjs derive-password <private_key> [pub  Derive password from private and pub
  lic_key]                                  lic key.
  wcbjs encrypt-private-key <passphrase> [  Encrypt private key with passphrase.
  filename]                                  Key either read from "filename" or
                                            STDIN.
  wcbjs decrypt-private-key <passphrase> [  Decrypt private key with passphrase.
  filename]                                  Key either read from "filename" or
                                            STDIN.
  wcbjs encrypt-private-key-to <private_ke  Encrypt private key with private and
  y> <public_key> [filename]                 public key. Private key either read
                                             from "filename" or STDIN.
  wcbjs decrypt-private-key-from <private_  Decrypt private key with private and
  key> <public_key> [filename]               public key. Private key either read
                                             from "filename" or STDIN.
  wcbjs encrypt-to <private_key> <public_k  Encrypt message with private and pub
  ey> [filename]                            lic key. Message either read from "f
                                            ilename" or STDIN.
  wcbjs decrypt-from <private_key> <public  Decrypt box with private and public
  _key> [filename]                          key. Box either read from "filename"
                                             or STDIN.

Options:
  --version  Show version number                                       [boolean]
  --help     Show help                                                 [boolean]

Note that for symmetric encryption the password is visible eg. in ps, so that's not recommended if you need strong security. Reach out to me if using environment variables instead would be good fit, I'd be happy to add it.
