krb5_rd_priv - Process a KRB-PRIV message.
============================================
..
.. c:function:: krb5_error_code krb5_rd_priv(krb5_context context, krb5_auth_context auth_context, const krb5_data * inbuf, krb5_data * outbuf, krb5_replay_data * outdata)
..
:param:
**[in]** **context** - Library context
**[in]** **auth_context** - Authentication structure
**[in]** **inbuf** - **KRB-PRIV** message to be parsed
**[out]** **outbuf** - Data parsed from **KRB-PRIV** message
**[out]** **outdata** - Replay data. Specify NULL if not needed
..
:retval:
- 0 Success; otherwise - Kerberos error codes
..
This function parses a **KRB-PRIV** message, verifies its integrity, and stores its unencrypted data into *outbuf* .
If the :data:`KRB5_AUTH_CONTEXT_DO_SEQUENCE` flag is set in *auth_context* , the sequence number of the KRB-SAFE message is checked against the remote sequence number field of *auth_context* . Otherwise, the sequence number is not used.
If the :data:`KRB5_AUTH_CONTEXT_DO_TIME` flag is set in *auth_context* , then two additional checks are performed:
- The timestamp in the message must be within the permitted clock skew (which is usually five minutes).
- The message must not be a replayed message field in *auth_context* .
..
.. note::
If the :data:`KRB5_AUTH_CONTEXT_RET_TIME` or :data:`KRB5_AUTH_CONTEXT_RET_SEQUENCE` flag is set in *auth_context* , *outdata* is required.
*auth_context* must have a remote address set. This address will be used to verify the sender address in the KRB-PRIV message. If *auth_context* has a local address set, it will be used to verify the receiver address in the KRB-PRIV message if the message contains one. Both addresses must use type **ADDRTYPE_ADDRPORT** .
