 *pcreddata* will be decrypted using the receiving subkey if it is present in *auth_context* , or the session key if the receiving subkey is not present or fails to decrypt the message.



Use :c:func:`krb5_free_tgt_creds()` to free *pppcreds* when it is no longer needed.

.. note::

	 The *outdata* argument is required if :data:`KRB5_AUTH_CONTEXT_RET_TIME` or :data:`KRB5_AUTH_CONTEXT_RET_SEQUENCE` flag is set in the *auth_context* .`
