NAME

shishi_kdc_check_nonce - API function

SYNOPSIS

#include <shishi.h>

int shishi_kdc_check_nonce(Shishi * handle, Shishi_asn1 kdcreq, Shishi_asn1 enckdcreppart);

ARGUMENTS

Shishi * handle

Shishi handle as allocated by shishi_init().

Shishi_asn1 kdcreq

Request of type KDC-REQ.

Shishi_asn1 enckdcreppart

Encrypted KDC-REP part.

DESCRIPTION

Verifies that kdcreq.req-body.nonce and enckdcreppart.nonce contain matching values. This is one of the steps that has to be performed when processing an exchange of KDC-REQ and KDC-REP.

RETURN VALUE

Returns SHISHI_OK if successful, SHISHI_NONCE_MISMATCH whenever the nonces are of differing lengths (usually a sign that a buggy server truncates the nonce to 4 bytes) and the same code if the nonce values differ, or an error code otherwise.
