    FC_GetInfo - return general information about the PKCS #11 library.


    CK_RV  FC_GetInfo(CK_INFO_PTR pInfo);


    FC_GetInfo has one parameter:

    points to a CK_INFO structure


    FC_GetInfo returns general information about the PKCS #11 library. On return, the CK_INFO structure that pInfo points to has the following information:

    • cryptokiVersion: PKCS #11 interface version number implemented by the PKCS #11 library. The version is 2.20 (major=0x02, minor=0x14).
    • manufacturerID: the PKCS #11 library manufacturer, "Mozilla Foundation", padded with spaces to 32 characters and not null-terminated.
    • flags: should be 0.
    • libraryDescription: description of the library, "NSS Internal Crypto Services", padded with spaces to 32 characters and not null-terminated.
    • libraryVersion: PKCS #11 library version number, for example, 3.11 (major=0x03, minor=0x0b).

    A user may call FC_GetInfo without logging into the token (to assume the NSS User role).

    Return value

    FC_GetInfo always returns CKR_OK.

    FC_GetInfo should return CKR_ARGUMENTS_BAD if pInfo is NULL.

    FC_GetInfo should return CKR_CRYPTOKI_NOT_INITIALIZED if the library is not initialized.


    Note the use of the %.32s format string to print the manufacturerID and libraryDescription members of the CK_INFO structure.
