| =head1 NAME |
| |
| DH_size, DH_bits - get Diffie-Hellman prime size |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/dh.h> |
| |
| int DH_size(const DH *dh); |
| |
| int DH_bits(const DH *dh); |
| |
| =head1 DESCRIPTION |
| |
| DH_size() returns the Diffie-Hellman prime size in bytes. It can be used |
| to determine how much memory must be allocated for the shared secret |
| computed by DH_compute_key(). |
| |
| DH_bits() returns the number of significant bits. |
| |
| B<dh> and B<dh-E<gt>p> must not be B<NULL>. |
| |
| =head1 RETURN VALUE |
| |
| The size. |
| |

| L<BN_num_bits(3)> |
| |
| =head1 HISTORY |
| |
| DH_bits() was added in OpenSSL 1.1.0. |
