pkcs15-tool 1 opensc pkcs15-tool utility for manipulating PKCS #15 data structures on smart cards and similar security tokens pkcs15-tool [OPTIONS] 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. --learn-card, -L Cache PKCS #15 token data to the local filesystem. Subsequent operations are performed on the cached data where possible. If the cache becomes out-of-sync with the token state (eg. new key is generated and stored on the token), the cache should be updated or operations may show stale results. --list-applications List the on-card PKCS#15 applications --read-certificate cert, -r cert Reads the certificate with the given id. --list-certificates, -c Lists all certificates stored on the token. --read-data-object cert, -R data Reads data object with OID, applicationName or label. --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) --list-data-objects, -C Lists 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-pins Lists all PINs stored on the token. General information about each PIN is listed (eg. PIN name). Actual PIN values are not shown. --dump, -D Dump card objects. --change-pin Changes a PIN or PUK stored on the token. User authentication is required for this operation. --unblock-pin, -u Unblocks a PIN stored on the token. Knowledge of the Pin Unblock Key (PUK) is required for this operation. --list-keys, -k Lists 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-public-keys Lists all public keys stored on the token, including key name, id, algorithm and length information. --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. --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. --no-cache Disables token data caching. --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. --aid aid Specify in a hexadecimal form the AID of the on-card PKCS#15 application to be binded to. --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. --verbose, -v Causes pkcs15-tool to be more verbose. Specify this flag several times to enable debug output in the OpenSC library. pkcs15-init(1), pkcs15-crypt(1)
