Field Length (2 bytes): The size, in little-endian byte order, of the structure in bytes.

Algorithm ObjId Length (2 bytes): The size, in little-endian byte order, of the Algorithm ObjId string in bytes. MUST be set to 0x0014 (20 bytes).

Reserved (2 bytes): MUST be set to zero when sent and MUST be ignored on receipt.

PublicKey cbData (2 bytes): The size, in little-endian byte order, of the PublicKey Data field, in bytes. MUST be 0x008C.

PublicKey Unused (1 byte): MUST be set to zero when sent and MUST be ignored on receipt.

Algorithm ObjId (variable): An ASCII ASN.1-encoded object identifier (OID) indicating the public key format, MUST be the same as the rsaEncryption, as specified in [RFC8017] section A.1.

PublicKey Data (variable): An ASN.1-encoded 1024-bit RSA public key, as specified in [RFC8017] section A.1.1.
