The openpgp-tool utility is used for accessing data from the OpenPGP v1.1 and v2.0 smart cards and compatible tokens like e.g. GPF CryptoStick v1.x, which might not be present in PKCS#15 objects but available in custom files on the card. The data can be printed on screen or used by other programs via environment variables.
--exec prog, -x progExecute the given program with data in environment variables.
--help, -hPrint help message on screen.
--rawPrint values in raw format, as they are stored on the card.
--prettyPrint values in pretty format.
--user-info, -UShow card holder information.
--reader num, -r numUse the given reader. The default is the first reader with a card.
--verify pintypeVerify PIN (CHV1, CHV2 or CHV3).
--pin stringThe PIN text to verify. If set to env:VARIABLE, the value of the environment variable VARIABLE is used.
--gen-key ID, -G IDGenerate key. Specify key ID (1, 2 or 3) to generate.
--key-length bitlength, -L bitlengthLength (default 2048 bit) of the key to be generated.
--version, -VPrint the version of the utility and exit.
--verbose, -vVerbose operation. Use several times to enable debug output.
