<span>此类用于保护对属于特定<code>Subject</code>私有凭据的访问。</span>

<span>该<code>Subject</code>由一组校长表示。</span>
|

<p> <span>此<code>Permission</code>的目标名称指定了凭证类名称和一组主体。</span> <span>此权限操作的唯一有效值是“读取”。</span> <span>目标名称必须遵守以下语法：</span> </p>
|

<pre> <span>CredentialClass {PrincipalClass "PrincipalName"}*</span> </pre>
|
||
<span>例如，以下权限授予对主体拥有的com.sun.PrivateCredential的访问权限，该对象具有名称为“duke”的com.sun.Principal。</span>
|

<span>请注意，尽管此示例以及以下所有示例在grant语句中不包含Codebase，SignedBy或Principal信息（出于简单的原因），但实际的策略配置应在适当时指定该信息。</span>

<span>如果CredentialClass为“*”，则授予对属于指定的Subject的所有私有凭据的访问<code>Subject</code> 。</span>

<span>如果“PrincipalName”为“*”，那么授权给具有指定的<code>Principal</code> （实际PrincipalName无关紧要）的任何<code>Subject</code>所拥有的指定<code>Principal</code>的访问<code>Principal</code> 。</span>

<pre> <span>grant {

permission javax.security.auth.PrivateCredentialPermission

"a.b.Credential a.b.Principal "*"",

|
||
<span>如果PrincipalClass和“PrincipalName”均为“*”，则访问权限将被授予由任何<code>Subject</code>拥有的指定<code>Subject</code> 。</span>
|

<p> <span>此外，可以重复PrincipalClass / PrincipalName配对：</span> </p>
|

<pre> <span>grant {

"a.b.Credential a.b.Principal "duke" c.d.Principal "dukette"",

<span>上述授权访问私有证书，“abCredential”，属于<code>Subject</code>与至少两个相关联的校长：“abPrincipal”的名称，“公爵”和“cdPrincipal”，名称为“dukette”。</span>
