8This is a register for DH groups from RFC 3526 and RFC 4306.

9At this time the groups from RFC 7919 have not been registered by openssl,

10thus they cannot be imported from the cryptography library.

12We also provide TLS identifiers for these DH groups and also the ECDH groups.

13(Note that the equivalent of _ffdh_groups for ECDH is ec._CURVE_TYPES.)
