GOST R 34.10-2001 public key objects

GOST R 34.10-2001 public key objects (object class CKO_PUBLIC_KEY, key type CKK_GOSTR3410) hold GOST R 34.10-2001 public keys.

The following table defines the GOST R 34.10-2001 public key object attributes, in addition to the common attributes defined for this object class:

Table 211, GOST R 34.10-2001 Public Key Object Attributes

Attribute	Data Type	Meaning
CKA_VALUE^1,4	Byte array	64 bytes for public key; 32 bytes for each coordinates X and Y of elliptic curve point P(X, Y) in little endian order
CKA_GOSTR3410PARAMS^1,3	Byte array	DER-encoding of the object identifier indicating the data object type of GOST R 34.10-2001. When key is used the domain parameter object of key type CKK_GOSTR3410 must be specified with the same attribute CKA_OBJECT_ID
CKA_GOSTR3411PARAMS^1,3,8	Byte array	DER-encoding of the object identifier indicating the data object type of GOST R 34.11-94. When key is used the domain parameter object of key type CKK_GOSTR3411 must be specified with the same attribute CKA_OBJECT_ID
CKA_GOST28147_PARAMS⁸	Byte array	DER-encoding of the object identifier indicating the data object type of GOST 28147-89. When key is used the domain parameter object of key type CKK_GOST28147 must be specified with the same attribute CKA_OBJECT_ID. The attribute value may be omitted

The following is a sample template for creating an GOST R 34.10-2001 public key object:

CK_BYTE value[64] = {...};
CK_BBOOL true = CK_TRUE;
