+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBBN_BLINDING_new()\fR allocates a new \fB\s-1BN_BLINDING\s0\fR structure and copies
+the \fBA\fR and \fBAi\fR values into the newly created \fB\s-1BN_BLINDING\s0\fR object.
+.PP
+\&\fBBN_BLINDING_free()\fR frees the \fB\s-1BN_BLINDING\s0\fR structure.
+If \fBb\fR is \s-1NULL,\s0 nothing is done.
+.PP
+\&\fBBN_BLINDING_update()\fR updates the \fB\s-1BN_BLINDING\s0\fR parameters by squaring
+the \fBA\fR and \fBAi\fR or, after specific number of uses and if the
+necessary parameters are set, by re-creating the blinding parameters.
+.PP
+\&\fBBN_BLINDING_convert_ex()\fR multiplies \fBn\fR with the blinding factor \fBA\fR.
+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_is_current_thread()\fR returns whether the \fB\s-1BN_BLINDING\s0\fR
+structure is owned by the current thread. This is to help users
+provide proper locking if needed for multi-threaded use.
+.PP
+\&\fBBN_BLINDING_set_current_thread()\fR sets the current thread as the
+owner of the \fB\s-1BN_BLINDING\s0\fR structure.
+.PP
+\&\fBBN_BLINDING_lock()\fR locks the \fB\s-1BN_BLINDING\s0\fR structure.
+.PP
+\&\fBBN_BLINDING_unlock()\fR unlocks the \fB\s-1BN_BLINDING\s0\fR structure.
+.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_is_current_thread()\fR returns 1 if the current thread owns
+the \fB\s-1BN_BLINDING\s0\fR object, 0 otherwise.
+.PP
+\&\fBBN_BLINDING_set_current_thread()\fR doesn't return anything.
+.PP
+\&\fBBN_BLINDING_lock()\fR, \fBBN_BLINDING_unlock()\fR return 1 if the operation
+succeeded or 0 on error.
+.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 "HISTORY"
+.IX Header "HISTORY"
