# shishi\_tgs\_process(3)

API function

## NAME

shishi\_tgs\_process - API function

## SYNOPSIS

**#include \<shishi.h\>**

**int shishi\_tgs\_process(Shishi \*** *handle***, Shishi\_asn1** *tgsreq***, Shishi\_asn1** *tgsrep***, Shishi\_asn1** *authenticator***, Shishi\_asn1** *oldenckdcreppart***, Shishi\_asn1 \*** *enckdcreppart***);**

## ARGUMENTS

- Shishi \* handle

  Shishi handle as allocated by **shishi\_init()**.

- Shishi\_asn1 tgsreq

  Input variable holding the transmitted KDC-REQ.

- Shishi\_asn1 tgsrep

  Input variable holding the received KDC-REP.

- Shishi\_asn1 authenticator

  Input variable with an authenticator extracted from the AP-REQ part of *tgsreq*.

- Shishi\_asn1 oldenckdcreppart

  Input variable with EncKDCRepPart used in the request.

- Shishi\_asn1 \* enckdcreppart

  Output variable holding the new EncKDCRepPart.

## DESCRIPTION

Processes a TGS client exchange and outputs the decrypted EncKDCRepPart, holding details about the received ticket. This function simply derives the encryption key from the ticket used to construct the original TGS request, and then calls **shishi\_kdc\_process()**.

## RETURN VALUE

Returns **SHISHI\_OK** if the TGS client exchange was successful.  Failures include ASN.1 and TGS conditions.
