| =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)>. | |
| =head1 NOTE | |
| Be careful to avoid small subgroup attacks when using this. | |
