CDMF secret key objects

CDMF secret key objects (object class CKO_SECRET_KEY, key type CKK_CDMF) hold single-length CDMF keys. The following table defines the CDMF secret key object attributes, in addition to the common attributes listed in Table 14 , Table 18 , Table 24 , and Table 39 :

Table 51, CDMF Secret Key Object
Attribute Data type Meaning

CKA_VALUE^1,4,6,7 Byte array Key value (always 8 bytes long)

CDMF keys must always have their parity bits properly set in exactly the same fashion described for DES keys in FIPS PUB 46-2. Attempting to create or unwrap a CDMF key with incorrect parity will return an error.

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

CK_OBJECT_CLASS class = CKO_SECRET_KEY;
CK_KEY_TYPE keyType = CKK_CDMF;
CK_UTF8CHAR label[] = "A CDMF secret key object";
CK_BYTE value[8] = {...};
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_ENCRYPT, &true, sizeof(true)},
{CKA_VALUE, value, sizeof(value)}
};
