Generic secret key objects

Generic secret key objects (object class CKO_SECRET_KEY, key type CKK_GENERIC_SECRET) hold generic secret keys. These keys do not support encryption, decryption, signatures or verification; however, other keys can be derived from them. The following table defines the generic secret key object attributes, in addition to the common attributes listed in Table 15 , Table 19 , Table 25 , and Table 42 : 




 Table 43, Generic Secret Key Object Attributes   
Attribute Data type Meaning   


CKA_VALUE1,4,6,7 Byte array Key value (arbitrary length)   


CKA_VALUE_LEN2,3,6 CK_ULONG Length in bytes of key value  

 



The following is a sample template for creating a generic secret key object:



CK_OBJECT_CLASS class = CKO_SECRET_KEY;
CK_KEY_TYPE keyType = CKK_GENERIC_SECRET;
CK_UTF8CHAR label[] = "A generic secret key object";
CK_BYTE value[] = {...};
CK_BBOOL true = TRUE;
CK_ATTRIBUTE template[] = {
{CKA_CLASS, &class, sizeof(class)},
{CKA_KEY_TYPE, &keyType, sizeof(keyType)},
{CKA_TOKEN, &true, sizeof(true)},
{CKA_LABEL, label, sizeof(label)-1},
{CKA_DERIVE, &true, sizeof(true)},
{CKA_VALUE, value, sizeof(value)}
};
