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 or
       NID_ffdhe8192.

       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.
