DH_new_by_nid3ssl
Create or get dh named parameters
Usage
#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);
Overview
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 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() 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.
