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. - -=head1 RETURN VALUES - -RSA_blinding_on() returns 1 on success, and 0 if an error occurred. - -RSA_blinding_off() returns no value. - -=head1 SEE ALSO - -L<rsa(3)|rsa(3)>, L<rand(3)|rand(3)> - -=head1 HISTORY - -RSA_blinding_on() and RSA_blinding_off() appeared in SSLeay 0.9.0. - -=cut |
