5 DH_size, DH_bits - get Diffie-Hellman prime size
9 #include <openssl/dh.h>
11 int DH_size(const DH *dh);
13 int DH_bits(const DH *dh);
17 DH_size() returns the Diffie-Hellman prime size in bytes. It can be used
18 to determine how much memory must be allocated for the shared secret
19 computed by DH_compute_key().
21 DH_bits() returns the number of significant bits.
23 B<dh> and B<dh-E<gt>p> must not be B<NULL>.
31 L<dh(3)|dh(3)>, L<DH_generate_key(3)|DH_generate_key(3)>,
32 L<BN_num_bits(3)|BN_num_bits(3)>
36 DH_size() is available in all versions of SSLeay and OpenSSL.
37 DH_bits() was added in OpenSSL 1.1.0.
