BN_BLINDING_invert_ex() multiplies B<n> with the -inverse blinding factor B<Ai>. If B<r> is not NULL it will be used as -the inverse blinding. - -BN_BLINDING_convert() and BN_BLINDING_invert() are wrapper -functions for BN_BLINDING_convert_ex() and BN_BLINDING_invert_ex() -with B<r> set to NULL. - -BN_BLINDING_set_thread_id() and BN_BLINDING_get_thread_id() -set and get the "thread id" value of the B<BN_BLINDING> structure, -a field provided to users of B<BN_BLINDING> structure to help them -provide proper locking if needed for multi-threaded use. The -"thread id" of a newly allocated B<BN_BLINDING> structure is zero. - -BN_BLINDING_get_flags() returns the BN_BLINDING flags. Currently -there are two supported flags: B<BN_BLINDING_NO_UPDATE> and -B<BN_BLINDING_NO_RECREATE>. B<BN_BLINDING_NO_UPDATE> inhibits the -automatic update of the B<BN_BLINDING> parameters after each use -and B<BN_BLINDING_NO_RECREATE> inhibits the automatic re-creation -of the B<BN_BLINDING> parameters after a fixed number of uses (currently -32). In newly allocated B<BN_BLINDING> objects no flags are set. -BN_BLINDING_set_flags() sets the B<BN_BLINDING> parameters flags. - -BN_BLINDING_create_param() creates new B<BN_BLINDING> parameters -using the exponent B<e> and the modulus B<m>. B<bn_mod_exp> and -B<m_ctx> can be used to pass special functions for exponentiation -(normally BN_mod_exp_mont() and B<BN_MONT_CTX>). - -=head1 RETURN VALUES - -BN_BLINDING_new() returns the newly allocated B<BN_BLINDING> structure -or NULL in case of an error. - -BN_BLINDING_update(), BN_BLINDING_convert(), BN_BLINDING_invert(), -BN_BLINDING_convert_ex() and BN_BLINDING_invert_ex() return 1 on -success and 0 if an error occured. - -BN_BLINDING_get_thread_id() returns the thread id (a B<unsigned long> -value) or 0 if not set. - -BN_BLINDING_get_flags() returns the currently set B<BN_BLINDING> flags -(a B<unsigned long> value). - -BN_BLINDING_create_param() returns the newly created B<BN_BLINDING> -parameters or NULL on error. - -=head1 SEE ALSO - -L<bn(3)|bn(3)> - -=head1 HISTORY - -BN_BLINDING_convert_ex, BN_BLINDIND_invert_ex, BN_BLINDING_get_thread_id, -BN_BLINDING_set_thread_id, BN_BLINDING_set_flags, BN_BLINDING_get_flags -and BN_BLINDING_create_param were first introduced in OpenSSL 0.9.8 - -=head1 AUTHOR - -Nils Larsch for the OpenSSL project (http://www.openssl.org). - -=cut |
