ECDSA public key objects

ECDSA public key objects (object class CKO_PUBLIC_KEY, key type CKK_ECDSA) hold ECDSA public keys. See Section 12.3 for more information about ECDSA. The following table defines the ECDSA public key object attributes, in addition to the common attributes listed in Table 14 , Table 18 , Table 24 , and Table 25 : 




 Table 29, ECDSA Public Key Object Attributes   
Attribute Data type Meaning   


CKA_ECDSA_PARAMS1,3,6 Byte array DER-encoding of an X9.62 ECParameters value   


CKA_EC_POINT1,4,6 Byte array DER-encoding of X9.62 ECPoint value P   

 



The CKA_ECDSA_PARAMS attribute value is known as the "ECDSA parameters".


The following is a sample template for creating an ECDSA public key object:



CK_OBJECT_CLASS class = CKO_PUBLIC_KEY;
CK_KEY_TYPE keyType = CKK_ECDSA;
CK_UTF8CHAR label[] = "An ECDSA public key object";
CK_BYTE ecdsaParams[] = {...};
CK_BYTE ecPoint[] = {...};
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_ECDSA_PARAMS, ecdsaParams, sizeof(ecdsaParams)},
{CKA_EC_POINT, ecPoint, sizeof(ecPoint)}
};
