 =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().
+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>.
 
-=head1 RETURN VALUE
+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.
 
-The size.
