Part of the first round of the DTLS handshake is to digest the curve generator point, V point, X point, and the id string. The V and X points are already stored in octet point format in memory. But the curve generator point is stored in little endian format.

An additional helper function is requested to read out the curve parameters into a buffer in the octet point format defined in section 2.3.3 in SEC 1: Elliptic Curve Cryptography. Specifically the G point is required.

NOTE: An additional helper function may be required to read cryptokey values into system RAM if they are stored in the secure keystore.
