NAME

       pkcs15-tool - utility for manipulating PKCS #15 data structures on smart cards and similar
       security tokens

SYNOPSIS

       pkcs15-tool [OPTIONS]

DESCRIPTION

       The pkcs15-tool utility is used to manipulate the PKCS #15 data structures on smart cards
       and similar security tokens. Users can list and read PINs, keys and certificates stored on
       the token. User PIN authentication is performed for those operations that require it.

OPTIONS

       --version,
           Print the OpenSC package release version.

       --aid aid
           Specify in a hexadecimal form the AID of the on-card PKCS#15 application to bind to.

       --auth-id pin, -a pin
           Specifies the auth id of the PIN to use for the operation. This is useful with the
           --change-pin operation.

       --change-pin
           Changes a PIN or PUK stored on the token. User authentication is required for this
           operation.

       --dump, -D
           List all card objects.

       --list-applications
           List the on-card PKCS#15 applications

       --list-certificates, -c
           List all certificates stored on the token.

       --list-data-objects, -C
           List all data objects stored on the token. For some cards the PKCS#15 attributes of
           the private data objects are protected for reading and need the authentication with
           the User PIN. In such a case the --verify-pin option has to be used.

       --list-keys, -k
           List all private keys stored on the token. General information about each private key
           is listed (eg. key name, id and algorithm). Actual private key values are not
           displayed. For some cards the PKCS#15 attributes of the private keys are protected for
           reading and need the authentication with the User PIN. In such a case the --verify-pin
           option has to be used.

       --list-pins
           List all PINs stored on the token. General information about each PIN is listed (eg.
           PIN name). Actual PIN values are not shown.

       --list-public-keys
           List all public keys stored on the token, including key name, id, algorithm and length
           information.

       --short -s
           Output lists in compact format.

       --no-cache
           Disables token data caching.

       --clear-cache
           Removes the user's cache directory. On Windows, this option additionally removes the
           system's caching directory (requires administrator privileges).

       --clear-cache
           Removes the user's cache directory. On Windows, this option additionally removes the
           system's caching directory (requires administrator privileges).

       --output filename, -o filename
           Specifies where key output should be written. If filename already exists, it will be
           overwritten. If this option is not given, keys will be printed to standard output.

       --raw
           Changes how --read-data-object prints the content to standard output. By default, when
           --raw is not given, it will print the content in hex notation. If --raw is set, it
           will print the binary data directly. This does not affect the output that is written
           to the file specified by the --output option. Data written to a file will always be in
           raw binary.

       --read-certificate cert, -r cert
           Reads the certificate with the given id.

       --read-data-object cert, -R data
           Reads data object with OID, applicationName or label. The content is printed to
           standard output in hex notation, unless the --raw option is given. If an output file
           is given with the --output option, the content is additionally written to the file.
           Output to the file is always written in raw binary mode, the --raw only affects
           standard output behavior.

       --read-public-key id
           Reads the public key with id id, allowing the user to extract and store or use the
           public key.

       --read-ssh-key id
           Reads the public key with id id, writing the output in format suitable for
           $HOME/.ssh/authorized_keys.

           The key label, if any will be shown in the 'Comment' field.

           --rfc4716
               When used in conjunction with option --read-ssh-key the output format of the
               public key follows rfc4716.

           The default output format is a single line (openssh).

       --reader num
           Forces pkcs15-tool to use reader number num for operations. The default is to use
           reader number 0, the first reader in the system.

       --unblock-pin, -u
           Unblocks a PIN stored on the token. Knowledge of the Pin Unblock Key (PUK) is required
           for this operation.

       --verbose, -v
           Causes pkcs15-tool to be more verbose. Specify this flag several times to enable debug
           output in the OpenSC library.

       --verify-pin
           Verify PIN after card binding and before issuing any command (without 'auth-id' the
           first non-SO, non-Unblock PIN will be verified)

       --use-pinpad
           Do not prompt the user; if no PINs supplied, pinpad will be used.
