用Java讀取OCSP簽名證書時出現異常

Question

我目前正在努力使Java應用程序（JRE 1.5+）與Windows 2008 OCSP響應程序進行通訊，並且在嘗試讀取響應程序的簽名證書時遇到一個奇怪的錯誤。

我在嘗試執行OCSP驗證時遇到以下異常。

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)

    at sun.security.x509.X509CertInfo.parse(Unknown Source)

這表明閱讀簽名證書時出現問題，因此我嘗試使用類似於以下方法的方法分別導入該證書：

    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;
}

這給了我同樣的錯誤。 這似乎只發生在從OCSP簽名模板生成的證書中，可以很好地讀取用戶證書。

是否有人在Java中使用X509支持遇到類似問題？

問候，湯姆

Answer 1

我想你是這樣子的

  cf = CertificateFactory.getInstance("X509");

默認的X509工廠有很多限制。 看來您的證書包含工廠不知道如何解析的擴展名。 如果您發布證書，我可以幫助您確定有問題的擴展名。

編輯：令人討厭的擴展名是

1.3.6.1.5.5.7.48.1.5-id-pkix-ocsp-nocheck

唯一的選擇是使用Java內置JCE將其從證書中刪除。 您也可以嘗試其他的JCE，例如BouncyCastle。
