2.1. DIFFIE_HELLMAN
The following additional Group IDs MAY be used:
192-bit Random ECP Group | secp192r1 | 7
224-bit Random ECP Group | secp224r1 | 8
256-bit Random ECP Group | secp256r1 | 9
384-bit Random ECP Group | secp384r1 | 10
521-bit Random ECP Group | secp521r1 | 11
The groups are defined in RFC 5114
