    .SH "DESCRIPTION"

        .PP 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.

                        .PP --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.

                            .PP --change-pin

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