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