<h1 class="topictitle1">Creating a GSSCredential</h1>
|
||
|
|
<div><p>A GSSCredential contains all the cryptographic information necessary
|
||
|
|
to create a context on behalf of a principal and can contain credential information
|
||
|
|
for multiple mechanisms.</p>
|
||
|
|
<p>GSSManager has three credential creation methods. Two of the methods take
|
||
|
|
for parameters a GSSName, the lifetime of the credential, one or more mechanisms
|
||
|
|
from which to get credentials, and the credential usage type. The third method
|
||
|
|
takes only a usage type and uses the default values for other parameters.
|
||
|
|
Specifying a null mechanism also uses the default mechanism. Specifying a
|
||
|
|
null array of mechanisms causes the method to return credentials for the default
|
||
|
|
set of mechanisms.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Because IBM<sup>®</sup> JGSS
|
||
|
|
supports only the Kerberos V5 mechanism, that is the default mechanism.</div>
|
||
|
|
<p>Your application can create only one of the three credentials types (<var class="varname">initiate,</var> <var class="varname">accept</var>,
|
||
|
|
or <var class="varname">initiate and accept</var>) at a time.</p>
|
||
|
|
<ul><li>A context initiator creates <var class="varname">initiate</var> credentials</li>
|
||
|
|
<li>An acceptor creates <var class="varname">accept</var> credentials</li>
|
||
|
|
<li>An acceptor that also behaves as an initiator creates <var class="varname">initiate
|
||
|
|
and accept</var> credentials.</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>Examples: Obtaining credentials</strong></p>
|
||
|
|
<p>The following example obtains the default credentials for an initiator:</p>
|
||
|
|
<pre>GSSCredentials fooCreds = manager.createCredentials(GSSCredential.INITIATE)</pre>
|
||
|
|
<p>The following example obtains Kerberos V5 credentials for the initiator <em>foo</em> that
|
||
|
|
have the default validity period:</p>
|
||
|
|
<pre>GSSCredential fooCreds = manager.createCredential(fooName, GSSCredential.DEFAULT_LIFETIME,
|
||
|
|
krb5Mech,GSSCredential.INITIATE);</pre>
|
||
|
|
<p>The following example obtains an all-default acceptor credential:</p>
|
||
|
|
<pre>GSSCredential serverCreds = manager.createCredential(null, GSSCredential.DEFAULT_LIFETIME,
|
||
|
|
(Oid)null, GSSCredential.ACCEPT);</pre>
