=head1 NAME
|
||
|
|
|
||
|
|
DH_size, DH_bits, DH_security_bits - get Diffie-Hellman prime size and
|
||
|
|
security bits
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/dh.h>
|
||
|
|
|
||
|
|
The following functions have been deprecated since OpenSSL 3.0, and can be
|
||
|
|
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
||
|
|
see L<openssl_user_macros(7)>:
|
||
|
|
|
||
|
|
int DH_bits(const DH *dh);
|
||
|
|
|
||
|
|
int DH_size(const DH *dh);
|
||
|
|
|
||
|
|
int DH_security_bits(const DH *dh);
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The functions described on this page are deprecated.
|
||
|
|
Applications should instead use L<EVP_PKEY_get_bits(3)>,
|
||
|
|
L<EVP_PKEY_get_security_bits(3)> and L<EVP_PKEY_get_size(3)>.
|
||
|
|
|
||
|
|
DH_bits() returns the number of significant bits.
|
||
|
|
|
||
|
|
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
|
||
|
|
|
||
|
|
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_security_bits() returns the number of security bits of the given B<dh>
|
||
|
|
key. See L<BN_security_bits(3)>.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
DH_bits() returns the number of bits in the key, or -1 if
|
||
|
|
B<dh> doesn't hold any key parameters.
|
||
|
|
|
||
|
|
DH_size() returns the prime size of Diffie-Hellman in bytes, or -1 if
|
||
|
|
B<dh> doesn't hold any key parameters.
|
||
|
|
|
||
|
|
DH_security_bits() returns the number of security bits, or -1 if
|
||
|
|
B<dh> doesn't hold any key parameters.
