 =head1 DESCRIPTION
 
+All of the functions described on this page are deprecated.
+
 RSA is vulnerable to timing attacks. In a setup where attackers can
 measure the time of RSA decryption or signature operations, blinding
 must be used to protect the RSA operation from that attack.
 
 RSA_blinding_on() turns blinding on for key B<rsa> and generates a
-random blinding factor. B<ctx> is B<NULL> or a pre-allocated and
-initialized B<BN_CTX>. The random number generator must be seeded
-prior to calling RSA_blinding_on().

 RSA_blinding_off() turns blinding off and frees the memory used for
 the blinding factor.
