Twofish secret key objects

Twofish secret key objects (object class CKO_SECRET_KEY, key type CKK_TWOFISH) hold Twofish keys. The following table defines the Twofish secret key object attributes, in addition to the common attributes defined for this object class: 




 Table 147, Twofish Secret Key Object   
Attribute Data type Meaning   


CKA_VALUE1,4,6,7 Byte array Key value 128-, 192-, or 256-bit key   


CKA_VALUE_LEN2,3 CK_ULONG Length in bytes of key value  

 



- Refer to Table 15 for footnotes


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



CK_OBJECT_CLASS class = CKO_SECRET_KEY;
CK_KEY_TYPE keyType = CKK_TWOFISH;
CK_UTF8CHAR label[] = "A twofish secret key object";
CK_BYTE value[16] = {...};
CK_BBOOL true = CK_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_ENCRYPT, &true, sizeof(true)},
{CKA_VALUE, value, sizeof(value)}
};
