| 13 | =head1 DESCRIPTION
|
|---|
| 14 |
|
|---|
| 15 | DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q
|
|---|
| 16 | is lost during that conversion, but the resulting DH parameters
|
|---|
| 17 | contain its length.

| 19 | =head1 RETURN VALUES
|
|---|
| 20 |
|
|---|
| 21 | DSA_dup_DH() returns the new B<DH> structure, and NULL on error. The
|
|---|
| 22 | error codes can be obtained by L<ERR_get_error(3)>.
