|
||||
|
||||
All of the functions described on this page are deprecated.
|
||||
Applications should instead use L<EVP_PKEY_bits(3)>,
|
||||
L<EVP_PKEY_security_bits(3)> and L<EVP_PKEY_size(3)>.
|
||||
DH_bits() returns the number of significant bits.
|
||||
|
||||
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
||||
|
||||
The remaining functions described on this page are deprecated.
|
||||
Applications should instead use L<EVP_PKEY_security_bits(3)> and
|
||||
L<EVP_PKEY_size(3)>.
|
||||
|
||||
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 L<DH_compute_key(3)>.
|
||||
|
||||
DH_bits() returns the number of significant bits.
|
||||
|
||||
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
||||
|
||||
DH_security_bits() returns the number of security bits of the given B<dh>
|
||||
key. See L<BN_security_bits(3)>.

=head1 HISTORY
|
||||
|
||||
All of these functions were deprecated in OpenSSL 3.0.
|
||||
The DH_size() and DH_security_bits() functions were deprecated in OpenSSL 3.0.
|
||||
|
||||
The DH_bits() function was added in OpenSSL 1.1.0.
