NAME
DSA_dup_DH - create a DH structure out of DSA structure
SYNOPSIS
#include <openssl/dsa.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 *DSA_dup_DH(const DSA *r);
DESCRIPTION
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.
RETURN VALUES
DSA_dup_DH() returns the new DH structure, and NULL on error. The
error codes can be obtained by ERR_get_error(3).
NOTE
Be careful to avoid small subgroup attacks when using this.

HISTORY
This function was deprecated in OpenSSL 3.0.
