If \fBr\fR is not \s-1NULL\s0 a copy the inverse blinding factor \fBAi\fR will be returned in \fBr\fR (this is useful if a \fB\s-1RSA\s0\fR object is shared among several threads). \fBBN_BLINDING_invert_ex()\fR multiplies \fBn\fR with the inverse blinding factor \fBAi\fR. If \fBr\fR is not \s-1NULL\s0 it will be used as the inverse blinding. .PP \&\fBBN_BLINDING_convert()\fR and \fBBN_BLINDING_invert()\fR are wrapper functions for \fBBN_BLINDING_convert_ex()\fR and \fBBN_BLINDING_invert_ex()\fR with \fBr\fR set to \s-1NULL.\s0 .PP \&\fBBN_BLINDING_thread_id()\fR provides access to the \fB\s-1CRYPTO_THREADID\s0\fR object within the \fB\s-1BN_BLINDING\s0\fR structure. This is to help users provide proper locking if needed for multi-threaded use. The \*(L"thread id\*(R" object of a newly allocated \fB\s-1BN_BLINDING\s0\fR structure is initialised to the thread id in which \fBBN_BLINDING_new()\fR was called. .PP \&\fBBN_BLINDING_get_flags()\fR returns the \s-1BN_BLINDING\s0 flags. Currently there are two supported flags: \fB\s-1BN_BLINDING_NO_UPDATE\s0\fR and \&\fB\s-1BN_BLINDING_NO_RECREATE\s0\fR. \fB\s-1BN_BLINDING_NO_UPDATE\s0\fR inhibits the automatic update of the \fB\s-1BN_BLINDING\s0\fR parameters after each use and \fB\s-1BN_BLINDING_NO_RECREATE\s0\fR inhibits the automatic re-creation of the \fB\s-1BN_BLINDING\s0\fR parameters after a fixed number of uses (currently 32). In newly allocated \fB\s-1BN_BLINDING\s0\fR objects no flags are set. \&\fBBN_BLINDING_set_flags()\fR sets the \fB\s-1BN_BLINDING\s0\fR parameters flags. .PP \&\fBBN_BLINDING_create_param()\fR creates new \fB\s-1BN_BLINDING\s0\fR parameters using the exponent \fBe\fR and the modulus \fBm\fR. \fBbn_mod_exp\fR and \&\fBm_ctx\fR can be used to pass special functions for exponentiation (normally \fBBN_mod_exp_mont()\fR and \fB\s-1BN_MONT_CTX\s0\fR). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBN_BLINDING_new()\fR returns the newly allocated \fB\s-1BN_BLINDING\s0\fR structure or \s-1NULL\s0 in case of an error. .PP \&\fBBN_BLINDING_update()\fR, \fBBN_BLINDING_convert()\fR, \fBBN_BLINDING_invert()\fR, \&\fBBN_BLINDING_convert_ex()\fR and \fBBN_BLINDING_invert_ex()\fR return 1 on success and 0 if an error occurred. .PP \&\fBBN_BLINDING_thread_id()\fR returns a pointer to the thread id object within a \fB\s-1BN_BLINDING\s0\fR object. .PP \&\fBBN_BLINDING_get_flags()\fR returns the currently set \fB\s-1BN_BLINDING\s0\fR flags (a \fBunsigned long\fR value). .PP \&\fBBN_BLINDING_create_param()\fR returns the newly created \fB\s-1BN_BLINDING\s0\fR parameters or \s-1NULL\s0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBbn\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" BN_BLINDING_thread_id was first introduced in OpenSSL 1.0.0, and it deprecates BN_BLINDING_set_thread_id and BN_BLINDING_get_thread_id. .PP 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 .SH "AUTHOR" .IX Header "AUTHOR" Nils Larsch for the OpenSSL project (http://www.openssl.org).
