| |
| 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. |
