DH_NEW_BY_NID(3ossl) OpenSSL DH_NEW_BY_NID(3ossl)
NAME
DH_new_by_nid, DH_get_nid - create or get DH named parameters
SYNOPSIS
#include <openssl/dh.h>
The following functions have been deprecated since OpenSSL 3.0, and can
be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
version value, see openssl_user_macros(7):
DH *DH_new_by_nid(int nid);
int DH_get_nid(const DH *dh);
DESCRIPTION
DH_new_by_nid(3) 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 safe prime group. It returns the NID corresponding to the
matching parameters or NID_undef if there is no match. This function
is deprecated.
RETURN VALUES
DH_new_by_nid(3) returns a set of DH parameters or NULL if an error
occurred.
DH_get_nid() returns the NID of the matching set of parameters for p
and g and optionally q, otherwise it returns NID_undef if there is no
match.
HISTORY
All of these functions were deprecated in OpenSSL 3.0.
