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.
