FC_GetTokenInfo - obtain information about a particular token in the system.
FC_GetTokenInfo has two parameters:
- the ID of the token's slot
- points to a CK_TOKEN_INFO structure
FC_GetTokenInfo returns information about the token in the specified slot. On return, the
CK_TOKEN_INFO structure that
pInfo points to has the following information:
label: the label of the token, assigned during token initialization, padded with spaces to 32 bytes and not null-terminated.
manufacturerID: ID of the device manufacturer, "Mozilla Foundation", padded with spaces to 32 characters and not null-terminated.
model: model of the device, "NSS 3", padded with spaces to 16 characters and not null-terminated.
serialNumber: the device's serial number as a string, "0000000000000000", 16 characters and not null-terminated.
flags: bit flags indicating capabilities and status of the device.
CKF_RNG (0x00000001): this device has a random number generator
CKF_WRITE_PROTECTED (0x00000002): this device is read-only
CKF_LOGIN_REQUIRED (0x00000004): this device requires the user to log in to use some of its services
CKF_USER_PIN_INITIALIZED (0x00000008): the user's password has been initialized
CKF_DUAL_CRYPTO_OPERATIONS (0x00000200): a single session with the token can perform dual cryptographic operations
CKF_TOKEN_INITIALIZED (0x00000400): the token has been initialized. If login is required (which is true for the FIPS mode of operation), this flag means the user's password has been initialized.
ulSessionCount: number of sessions that this application currently has open with the token
ulRwSessionCount: number of read/write sessions that this application currently has open with the token
hardwareVersion: hardware version number, for example, 8.3 (
major=0x08, minor=0x03), which are the version numbers of the certificate and key databases, respectively.
firmwareVersion: firmware version number, 0.0 (
A user may call
FC_GetTokenInfo without logging into the token (to assume the NSS User role).
- Token information was successfully copied.
- The PKCS #11 module library is not initialized.
- The specified slot number is out of the defined range of values.
FC_GetTokenInfo should return CKR_ARGUMENTS_BAD if pInfo is NULL.
