 RSA_bits() returns the number of significant bits.
 
 B<rsa> and B<rsa-E<gt>n> must not be B<NULL>.
 
+The remaining functions described on this page are deprecated.
+Applications should instead use L<EVP_PKEY_size(3)>, L<EVP_PKEY_bits(3)>
+and L<EVP_PKEY_security_bits(3)>.

+RSA_size() returns the RSA modulus size in bytes. It can be used to

 RSA_security_bits() returns the number of security bits of the given B<rsa>
 key. See L<BN_security_bits(3)>.
