DH_new_by_nid, DH_get_nid - get or find DH named parameters
#include <openssl/dh.h>
DH *DH_new_by_nid(int nid);Deprecated since OpenSSL 3.0, can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see 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. This function is deprecated. 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. The DH_get_nid() function was deprecated in OpenSSL 3.0.
