DSAdupDH(3) OpenSSL DSAdupDH(3)

NAME
       DSAdupDH - create a DH structure out of DSA structure

SYNOPSIS
        #include 

        DH * DSAdupDH(const DSA *r);

DESCRIPTION
       DSAdupDH() duplicates DSA parameters/keys as DH parameters/keys. q is
       lost during that conversion, but the resulting DH parameters contain
       its length.

RREETTUURRNN VVAALLUUEE
       DSAdupDH() returns the new DDHH structure, and NULL on error. The error
       codes can be obtained by ERRgeterror(3).

NNOOTTEE
       Be careful to avoid small subgroup attacks when using this.
