+=head1 NAME
+
+BN_mod_inverse - compute inverse modulo n
+
+=head1 SYNOPSIS
+
+ #include <openssl/bn.h>
+
+ BIGNUM *BN_mod_inverse(BIGNUM *r, BIGNUM *a, const BIGNUM *n,
+                        BN_CTX *ctx);
+
+=head1 DESCRIPTION
+
+BN_mod_inverse() computes the inverse of B<a> modulo B<n>
+places the result in B<r> (C<(a*r)%n==1>). If B<r> is NULL,
+a new B<BIGNUM> is created.
+
+B<ctx> is a previously allocated B<BN_CTX> used for temporary
+variables. B<r> may be the same B<BIGNUM> as B<a> or B<n>.
+
+=head1 RETURN VALUES
+
+BN_mod_inverse() returns the B<BIGNUM> containing the inverse, and
+NULL on error. The error codes can be obtained by L<ERR_get_error(3)>.
