NAME
BN_mod_inverse - compute inverse modulo n
SYNOPSIS
Header "SYNOPSIS" .Vb 1
#include <openssl/bn.h>
\&
BIGNUM *BN_mod_inverse(BIGNUM *r, BIGNUM *a, const BIGNUM *n,
BN_CTX *ctx);
.Ve
DESCRIPTION
Header "DESCRIPTION" \fBBN_mod_inverse() computes the inverse of a modulo n
places the result in r (\*(C`(a*r)%n==1\*(C'). If r is NULL,
a new BIGNUM is created.
\fBctx is a previously allocated BN_CTX used for temporary variables. r may be the same BIGNUM as a.
NOTES
Header "NOTES" It is an error to use the same BIGNUM as n.
"RETURN VALUES"
Header "RETURN VALUES" \fBBN_mod_inverse() returns the BIGNUM containing the inverse, and
NULL on error. The error codes can be obtained by ERR_get_error\|(3).
