Deprecated since OpenSSL 3.0, can be hidden entirely by defining
B<OPENSSL_API_COMPAT> with a suitable version value, see
L<openssl_user_macros(7)>:
int DH_size(const DH *dh);

int DH_security_bits(const DH *dh);
=head1 DESCRIPTION
-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 RETURN VALUES
-DH_size() returns the prime size of Diffie-Hellman in bytes.
-
DH_bits() returns the number of bits in the key.
+DH_size() returns the prime size of Diffie-Hellman in bytes.
+
DH_security_bits() returns the number of security bits.

=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.
