| 13 | =head1 DESCRIPTION
|
|---|
| 14 |
|
|---|
| 15 | DH_new_by_nid() creates and returns a DH structure containing named parameters
|
|---|
| 16 | B<nid>. Currently B<nid> must be B<NID_ffdhe2048>, B<NID_ffdhe3072>,
|
|---|
| 17 | B<NID_ffdhe4096>, B<NID_ffdhe6144> or B<NID_ffdhe8192>.
|
|---|
| 18 |
|
|---|
| 19 | DH_get_nid() determines if the parameters contained in B<dh> match
|
|---|
| 20 | any named set. It returns the NID corresponding to the matching parameters or
|
|---|
| 21 | B<NID_undef> if there is no match.
|

| 22 |
|
|---|
| 23 | =head1 RETURN VALUES
|
|---|
| 24 |
|
|---|
| 25 | DH_new_by_nid() returns a set of DH parameters or B<NULL> if an error occurred.
|
|---|
| 26 |
|
|---|
| 27 | DH_get_nid() returns the NID of the matching set of parameters or
|
|---|
| 28 | B<NID_undef> if there is no match.
