14 DH_new_by_nid() creates and returns a DH structure containing named
15 parameters nid. Currently nid must be NID_ffdhe2048, NID_ffdhe3072,
16 NID_ffdhe4096, NID_ffdhe6144, NID_ffdhe8192, NID_modp_1536,
17 NID_modp_2048, NID_modp_3072, NID_modp_4096, NID_modp_6144 or
18 NID_modp_8192.
19
20 DH_get_nid() determines if the parameters contained in dh match any
21 named set. It returns the NID corresponding to the matching parameters
22 or NID_undef if there is no match.
23
25 DH_new_by_nid() returns a set of DH parameters or NULL if an error
26 occurred.
27
28 DH_get_nid() returns the NID of the matching set of parameters or
29 NID_undef if there is no match.
