DSA_DUP_DH(3)                       OpenSSL                      DSA_DUP_DH(3)
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 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.
