DSA_DUP_DH(3) OpenSSL DSA_DUP_DH(3)NAMEDSA_dup_DH - create a DH structure out of DSA structure
SYNOPSIS
#include <openssl/dsa.h>
DH * DSA_dup_DH(const DSA *r);
DESCRIPTIONDSA_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 VALUEDSA_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.
SEE ALSOdh(3), dsa(3), ERR_get_error(3)HISTORYDSA_dup_DH() was added in OpenSSL 0.9.4.
