SYNOPSIS

9        #include <openssl/dh.h>
10        DH *DH_new_by_nid(int nid);
11        int *DH_get_nid(const DH *dh);

DESCRIPTION

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 or NID_ffdhe8192.
17
18       DH_get_nid() determines if the parameters contained in dh match any
19       named set. It returns the NID corresponding to the matching parameters
20       or NID_undef if there is no match.
21

RETURN VALUES

23       DH_new_by_nid() returns a set of DH parameters or NULL if an error
24       occurred.
25
26       DH_get_nid() returns the NID of the matching set of parameters or
27       NID_undef if there is no match.
