NAME
       DH_new_by_nid, DH_get_nid - get or find DH named parameters
SYNOPSIS
        #include <openssl/dh.h>
        DH *DH_new_by_nid(int nid);
        int DH_get_nid(const DH *dh);
DESCRIPTION
       DH_new_by_nid() creates and returns a DH structure containing named
       parameters nid. Currently nid must be NID_ffdhe2048, NID_ffdhe3072,
       NID_ffdhe4096, NID_ffdhe6144, NID_ffdhe8192, NID_modp_1536,
       NID_modp_2048, NID_modp_3072, NID_modp_4096, NID_modp_6144 or
       NID_modp_8192.
       DH_get_nid() determines if the parameters contained in dh match any
       named set. It returns the NID corresponding to the matching parameters
       or NID_undef if there is no match.
RETURN VALUES
       DH_new_by_nid() returns a set of DH parameters or NULL if an error
       occurred.
       DH_get_nid() returns the NID of the matching set of parameters or
       NID_undef if there is no match.
