| 15 | =head1 DESCRIPTION | |
| 16 | ||
| 26c79d56 | 17 | DH_size() returns the Diffie-Hellman prime size in bytes. It can be used |
| 4486d0cd UM |
18 | to determine how much memory must be allocated for the shared secret |
| 19 | computed by DH_compute_key(). | |
| 20 | ||
| 26c79d56 KR |
21 | DH_bits() returns the number of significant bits. |
| 22 | ||
| 23 | B<dh> and B<dh-E<gt>p> must not be B<NULL>. | |
| 4486d0cd UM |
24 | |
| 25 | =head1 RETURN VALUE | |
| 26 | ||
| 26c79d56 | 27 | The size. |
