+=head1 NAME
+
+DSA_dup_DH - create a DH structure out of DSA structure
+
+=head1 SYNOPSIS
+
+ #include <openssl/dsa.h>
+
+ DH * DSA_dup_DH(const DSA *r);
+
+=head1 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.
+
+=head1 RETURN VALUE
+
+DSA_dup_DH() returns the new B<DH> structure, and NULL on error. The
+error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
+
+=head1 NOTE
+
+Be careful to avoid small subgroup attacks when using this.
+
+=head1 SEE ALSO
+
+L<dh(3)|dh(3)>, L<dsa(3)|dsa(3)>, L<ERR_get_error(3)|ERR_get_error(3)>
+
+=head1 HISTORY
+
+DSA_dup_DH() was added in OpenSSL 0.9.4.
