1krb5_mk_priv - Format a KRB-PRIV message. 2=========================================== 3 4.. 5 6.. c:function:: krb5_error_code krb5_mk_priv(krb5_context context, krb5_auth_context auth_context, const krb5_data * userdata, krb5_data * der_out, krb5_replay_data * rdata_out) 7 8.. 9 10 11:param: 12 13 **[in]** **context** - Library context 14 15 **[in]** **auth_context** - Authentication context 16 17 **[in]** **userdata** - User data for **KRB-PRIV** message 18 19 **[out]** **der_out** - Formatted **KRB-PRIV** message 20 21 **[out]** **rdata_out** - Replay data (NULL if not needed) 22 23 24.. 25 26 27:retval: 28 - 0 Success; otherwise - Kerberos error codes 29 30 31.. 32 33 34 35 36 37 38 39This function is similar to krb5_mk_safe(), but the message is encrypted and integrity-protected, not just integrity-protected. 40 41 42 43The local address in *auth_context* must be set, and is used to form the sender address used in the KRB-PRIV message. The remote address is optional; if specified, it will be used to form the receiver address used in the message. 44 45 46 47If the #KRB5_AUTH_CONTEXT_DO_TIME flag is set in *auth_context* , a timestamp is included in the KRB-PRIV message, and an entry for the message is entered in an in-memory replay cache to detect if the message is reflected by an attacker. If #KRB5_AUTH_CONTEXT_DO_TIME is not set, no replay cache is used. If #KRB5_AUTH_CONTEXT_RET_TIME is set in *auth_context* , a timestamp is included in the KRB-PRIV message and is stored in *rdata_out* . 48 49 50 51If either #KRB5_AUTH_CONTEXT_DO_SEQUENCE or #KRB5_AUTH_CONTEXT_RET_SEQUENCE is set, the *auth_context* local sequence number is included in the KRB-PRIV message and then incremented. If #KRB5_AUTH_CONTEXT_RET_SEQUENCE is set, the sequence number used is stored in *rdata_out* . 52 53 54 55Use krb5_free_data_contents() to free *der_out* when it is no longer needed. 56 57 58 59 60 61 62 63 64 65 66.. 67 68 69 70 71 72 73.. note:: 74 75 The *rdata_out* argument is required if the #KRB5_AUTH_CONTEXT_RET_TIME or #KRB5_AUTH_CONTEXT_RET_SEQUENCE flag is set in *auth_context* . 76 77 78 79 80
