java - 在 Java 中读取 OCSP 签名证书时出现异常

Question

我目前正在努力让 Java 应用程序 (JRE 1.5+) 与 Windows 2008 OCSP 响应程序通信，并且在尝试读取响应程序的签名证书时遇到奇怪的错误。

我在尝试执行 OCSP 验证时遇到以下异常。

Caused by: java.security.cert.CertificateParsingException: java.io.IOException: short read on DerValue buffer
    at sun.security.x509.X509CertInfo.<init>(Unknown Source)
    at sun.security.x509.X509CertImpl.parse(Unknown Source)

这表明读取签名证书时出现问题，因此我尝试使用类似于以下的方法单独导入该证书:

    public static List<Certificate> readCerts(String certFile,
        CertificateFactory cf, boolean withCRL) throws Exception {
    FileInputStream fis = new FileInputStream(certFile);
    BufferedInputStream bis = new BufferedInputStream(fis);

    List<Certificate> certs = new LinkedList<Certificate>();

    while (bis.available() > 0) {
        Certificate cert = cf
                .generateCertificate(bis);
        X509Certificate cx509 = (X509Certificate) cert;
        certs.add(cert);
    }

    return certs;
}

这给了我同样的错误。这似乎只发生在从 OCSP 签名模板生成的证书上，用户证书可以正常读取。

还有其他人遇到过 Java 中 X509 支持的类似问题吗？

问候，汤姆

更新:我遇到问题的证书如下:

Answer 1

我假设你的工厂是这样的，

  cf = CertificateFactory.getInstance("X509");

默认的 X509 工厂有很多限制。您的证书似乎包含工厂不知道如何解析的扩展名。如果您发布证书，我可以帮助您识别有问题的扩展。

编辑:有问题的扩展是

1.3.6.1.5.5.7.48.1.5 - id-pkix-ocsp-nocheck

唯一的选择是使用 Java 内置 JCE 从证书中删除它。您还可以尝试其他 JCE，例如 BouncyCaSTLe。
