<p>The <em>SSL_Init_Application()</em> function is used to establish the SSL
|
||
|
|
security information to be used for all SSL sessions for the current job based
|
||
|
|
on the specified application identifier. The <em>SSL_Init_Application()</em>
|
||
|
|
API uses the application identifier to determine and then establish the
|
||
|
|
certificate and the associated public and private key information for use by
|
||
|
|
the SSL handshake protocol processing when acting as a server or when acting as
|
||
|
|
a client. The certificate and key information is needed by an application
|
||
|
|
that is acting as a client in the situaitons where the client is connecting to
|
||
|
|
a server which has enabled and requires client authentication.</p>

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Before the <em>SSL_Init_Application()</em> API can be used, the user must
|
||
|
|
have registered the application using the Register Application for Certificate
|
||
|
|
Use (OPM, QSYRGAP; ILE, QsyRegisterAppForCertUse) API. The Register Application
|
||
|
|
For Certificate Use API registers an application with the registry facility,
|
||
|
|
allowing an application to be associated with a specific certificate. The
|
||
|
|
Register Application for Certificate Use is described in the System Programming
|
||
|
|
Interface Reference. If the applicaiton is not registered with the registry
|
||
|
|
facility, then an error of SSL_ERROR_NOT_REGISTERED will be returned by
|
||
|
|
<em>SSL_Init_Application()</em>.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>A successful <em>SSL_Init()</em>, <em>SSL_Init (using NLS-enabled path name)</em>, or an <em>SSL_Init_Application()</em> API
|
||
|
|
must be used to enable a job for SSL processing before attempting to use any
|
||
|
|
other SSL API.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>If multiple <em>SSL_Init_Application()</em>, <em>SSL_Init (using NLS-enabled path name)</em>,
|
||
|
|
or multiple <em>SSL_Init()</em> APIs are
|
||
|
|
performed in a job, then only the values associated with the last
|
||
|
|
<em>SSL_Init_Application()</em>, <em>SSL_Init (using NLS-enabled path name)</em>, or <em>SSL_Init()</em> performed are
|
||
|
|
used.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>If the <em>SSL_Init_Application()</em> API or <em>SSL_Init()</em> API are
|
||
|
|
both performed in the same job, then only the values associated with the last
|
||
|
|
API performed are used.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The reserved fields in the <strong><em>SSLInitApp</em></strong> structure
|
||
|
|
must be set to NULLs (0s) before using this API.</li>
|
||
|
|
</ol>
|
||

|
|
