java - Opensaml key 信息配置

Question

我和我的团队正在使用 opensaml 生成 SAML token 。我们已经设法完成此设置，但另一个团队的成员告诉我们，如果我们能够对生成的 token 进行一些配置，他们将不胜感激。

他们希望我们更改的区域是 token 的 EncryptedKey 部分。目前，它看起来像这样:

我的同事希望它看起来像这样:

   </xenc:CipherData>
</xenc:EncryptedKey>

如您所见，不同之处在于后一个示例中的 SAML token 中没有添加 X509 证书，有关 key 的唯一信息是 key 名称。

经过调查，我认为问题可能出在凭证上。

有人有以这种方式配置 opensaml 的经验吗？怎么可能这样配置KeyInfo？

预先感谢您的帮助。

更新:我现在已经使用 KeyInfoHelper.addKeyName(KeyInfo, KeyName); 弄清楚了如何设置 key 名，但仍然无法隐藏 X509 证书信息。

Answer 1

这是 OpenSAML 3+ 版本。

private KeyInfo getKeyInfo(Credential c, String keyNameValue) {
    KeyName keyName = new KeyNameBuilder().buildObject();
    keyName.setValue(keyNameValue);
    EncryptionConfiguration secConfiguration = SecurityConfigurationSupport.getGlobalEncryptionConfiguration();
    NamedKeyInfoGeneratorManager namedKeyInfoGeneratorManager = secConfiguration.getDataKeyInfoGeneratorManager();
    KeyInfoGeneratorManager keyInfoGeneratorManager = namedKeyInfoGeneratorManager.getDefaultManager();
    KeyInfoGeneratorFactory keyInfoGeneratorFactory = keyInfoGeneratorManager.getFactory(credential);
    KeyInfoGenerator keyInfoGenerator = keyInfoGeneratorFactory.newInstance();
    KeyInfo keyInfo = keyInfoGenerator.generate(credential);
    keyInfo.getKeyNames().add(keyName);
    keyInfo.getX509Datas().clear();
    return keyInfo;             
}
