NAME
DSA_dup_DH — create a DH structure out of DSA structure
Synopsis
#include <openssl/dsa.h>
DH
* DSA_dup_DH(const DSA *r);
DESCRIPTION
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 VALUE
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
DSA_dup_DH() was added in OpenSSL 0.9.4.
