| 18 | =head1 DESCRIPTION
|
|---|
| 19 |
|
|---|
| 20 | DH_size() returns the Diffie-Hellman prime size in bytes. It can be used
|
|---|
| 21 | to determine how much memory must be allocated for the shared secret
|
|---|
| 22 | computed by L<DH_compute_key(3)>.
|
|---|
| 23 |
|
|---|
| 24 | DH_bits() returns the number of significant bits.
|
|---|
| 25 |
|
|---|
| 26 | B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
|---|
| 27 |
|
|---|
| 28 | DH_security_bits() returns the number of security bits of the given B<dh>
|
|---|
| 29 | key. See L<BN_security_bits(3)>.
|
|---|
| 30 |
|
|---|
| 31 | =head1 RETURN VALUES
|
|---|
| 32 |
|
|---|
| 33 | DH_size() returns the prime size of Diffie-Hellman in bytes.
|
|---|
| 34 |
|
|---|
| 35 | DH_bits() returns the number of bits in the key.
|
|---|
| 36 |
|
|---|
| 37 | DH_security_bits() returns the number of security bits.
