NAME
DSA_dup_DH - create a DH structure out of DSA structure
SYNOPSIS
#include <openssl/dsa.h>
Deprecated since OpenSSL 3.0, can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see DH *DSA_dup_DH(const DSA *r);
The function described on this page is deprecated. There is no direct replacement, applications should use the EVP_PKEY APIs for Diffie-Hellman operations. DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q is lost during that conversion, but the resulting DH parameters contain its length. DSA_dup_DH() returns the new DH structure, and NULL on error. The error codes can be obtained by NOTE
Be careful to avoid small subgroup attacks when using this. DSA_new(3), HISTORY
