14 DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q is
15 lost during that conversion, but the resulting DH parameters contain
16 its length.

19 DSA_dup_DH() returns the new DH structure, and NULL on error. The error
20 codes can be obtained by ERR_get_error(3).
21
23 Be careful to avoid small subgroup attacks when using this.
