1 krb5_rd_safe - Process KRB-SAFE message.
2 ==========================================
6 .. c:function:: krb5_error_code krb5_rd_safe(krb5_context context, krb5_auth_context auth_context, const krb5_data * inbuf, krb5_data * outbuf, krb5_replay_data * outdata)
13 **[in]** **context** - Library context
15 **[in]** **auth_context** - Authentication context
17 **[in]** **inbuf** - **KRB-SAFE** message to be parsed
19 **[out]** **outbuf** - Data parsed from **KRB-SAFE** message
21 **[out]** **outdata** - Replay data. Specify NULL if not needed
28 - 0 Success; otherwise - Kerberos error codes
39 This function parses a **KRB-SAFE** message, verifies its integrity, and stores its data into *outbuf* .
43 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.
47 If the :data:`KRB5_AUTH_CONTEXT_DO_TIME` flag is set in *auth_context* , then two additional checks are performed:
49 - The timestamp in the message must be within the permitted clock skew (which is usually five minutes).
52 - The message must not be a replayed message field in *auth_context* .
54 Use :c:func:`krb5_free_data_contents()` to free *outbuf* when it is no longer needed.
74 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* .
76 *auth_context* must have a remote address set. This address will be used to verify the sender address in the KRB-SAFE message. If *auth_context* has a local address set, it will be used to verify the receiver address in the KRB-SAFE message if the message contains one. Both addresses must use type **ADDRTYPE_ADDRPORT** .
