-=head1 DESCRIPTION
+ int RSA_size(const RSA *rsa);
-RSA_size() returns the RSA modulus size in bytes. It can be used to
-determine how much memory must be allocated for an RSA encrypted
-value.
+ int RSA_security_bits(const RSA *rsa);
+
+=head1 DESCRIPTION
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
+determine how much memory must be allocated for an RSA encrypted
+value.
+
RSA_security_bits() returns the number of security bits of the given B<rsa>
key. See L<BN_security_bits(3)>.
=head1 RETURN VALUES
-RSA_size() returns the size of modulus in bytes.
+RSA_bits() returns the number of bits in the key.
-DSA_bits() returns the number of bits in the key.
+RSA_size() returns the size of modulus in bytes.
RSA_security_bits() returns the number of security bits.
=head1 HISTORY
-RSA_bits() was added in OpenSSL 1.1.0.
+The RSA_size() and RSA_security_bits() functions were deprecated in OpenSSL 3.0.
+
+The RSA_bits() function was added in OpenSSL 1.1.0.
