# shishi\_kdc\_check\_nonce(3)

API function

## 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.
