Meta Objects are opaque objects with algorithm opaque-data that store the values of CKA_ID and CKA_LABEL attributes of another object on the YubiHSM 2, thus working around the hard limit on the length of those values and the inability to change those attributes after the fact. The number of attributes in the array is the ulValueLen component of the attribute divided by the size of CK_ATTRIBUTE. In general, the SafeNet ProtectToolkit -C system will define the object’s attributes. Somewhat unexpected, but not all that illogical. By default, however, the key that resides on slot 9C has its CKA_ALWAYS_AUTHENTICATE attribute set to True, which prompts the user for the PIN during the different operations, and so the right PIN can be entered at the right time.
