<p>This function creates an integrity protected <strong>KRB-SAFE</strong> message using data supplied by the application.</p>
<p>Fields in <em>auth_context</em> specify the checksum type, the keyblock that can be used to seed the checksum, full addresses (host and port) for the sender and receiver, and KRB5_AUTH_CONTEXT flags.</p>
<p>The local address in <em>auth_context</em> must be set, and is used to form the sender address used in the KRB-SAFE message. The remote address is optional; if specified, it will be used to form the receiver address used in the message.</p>
<p>If the #KRB5_AUTH_CONTEXT_DO_TIME flag is set in <em>auth_context</em> , a timestamp is included in the KRB-SAFE 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 <em>auth_context</em> , a timestamp is included in the KRB-SAFE message and is stored in <em>rdata_out</em> .</p>
<p>If either #KRB5_AUTH_CONTEXT_DO_SEQUENCE or #KRB5_AUTH_CONTEXT_RET_SEQUENCE is set, the <em>auth_context</em> local sequence number is included in the KRB-SAFE message and then incremented. If #KRB5_AUTH_CONTEXT_RET_SEQUENCE is set, the sequence number used is stored in <em>rdata_out</em> .</p>
<p>Use krb5_free_data_contents() to free <em>der_out</em> when it is no longer needed.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The <em>rdata_out</em> argument is required if the #KRB5_AUTH_CONTEXT_RET_TIME or #KRB5_AUTH_CONTEXT_RET_SEQUENCE flag is set in <em>auth_context</em> .</p>
