java - X509TrustManager 在不允许所有证书的情况下覆盖？

Question

我目前正在覆盖 X509TrustManager 以允许所有证书作为临时“解决方案”(当时是不安全的解决方案)。我试图弄清楚我将如何添加，以便它只接受我遇到问题的特定证书，直到可以完成正确的修复(目前不在我手中)。这是当前代码。

TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
    @Override
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    @Override
    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }

    @Override
    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }
}};

try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (GeneralSecurityException e) {
    System.out.println(e.getStackTrace());
}

Answer 1

您需要做的就是从 getAcceptedIssuers 返回证书。参见 this

 InputStream inStream = new FileInputStream("fileName-of-cert");
 CertificateFactory cf = CertificateFactory.getInstance("X.509");
 X509Certificate cert = (X509Certificate)cf.generateCertificate(inStream);
 inStream.close();

然后在方法中将其返回到一个数组中
