这看起来是一个标准问题，但我在任何地方都找不到明确的方向。
我有java代码试图连接到一个可能自签名(或过期)证书的服务器。代码报告以下错误:
[HttpMethodDirector] I/O exception (javax.net.ssl.SSLHandshakeException) caught
when processing request: sun.security.validator.ValidatorException: PKIX path
building failed: sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
根据我的理解，我必须使用keytool并告诉java允许此连接是OK的。
解决此问题的所有说明都假设我完全熟练使用keytool，例如
为服务器生成私有密钥并将其导入密钥存储库
有人能给我详细说明吗?
我正在运行unix，所以bash脚本将是最好的。
不确定这是否重要，但在jboss中执行的代码。
信任所有SSL证书:—
如果希望在测试服务器上进行测试，可以绕过SSL。
但是不要将此代码用于生产。
public static class NukeSSLCerts {
protected static final String TAG = "NukeSSLCerts";
public static void nuke() {
try {
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
X509Certificate[] myTrustedAnchors = new X509Certificate[0];
return myTrustedAnchors;
}
@Override
public void checkClientTrusted(X509Certificate[] certs, String authType) {}
@Override
public void checkServerTrusted(X509Certificate[] certs, String authType) {}
}
};
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
});
} catch (Exception e) {
}
}
}
请在Activity或应用程序类的onCreate()函数中调用此函数。
NukeSSLCerts.nuke();
这可以用于Android的Volley。

受下面annser的启发，我找到了一种信任自签名CA并保持信任默认CA的方法。
File file = new File(System.getProperty("java.home"), "lib/security/cacerts");
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(new FileInputStream(file), "changeit".toCharArray());
InputStream resourceAsStream = getClass().getClassLoader().getResourceAsStream("testCer.cer");
Certificate certificate = CertificateFactory.getInstance("X.509").generateCertificate(resourceAsStream);
keyStore.setCertificateEntry("my-server-alias", certificate);
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(keyStore);
SSLContext sslContext = SSLContexts.createDefault();
sslContext.init(null, trustManagerFactory.getTrustManagers(), null);
// check domain
// SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext);
// not check domain
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext,
new String[]{"TLSv1","TLSv1.1","TLSv1.2","SSLv3"},null, NoopHostnameVerifier.INSTANCE);
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
factory.setHttpClient(httpClient);
RestTemplate restTemplate = new RestTemplate(factory);
而不是设置默认的套接字工厂(这在我看来是一件坏事)- yhis只会影响当前连接，而不是你试图打开的每一个SSL连接:
URLConnection connection = url.openConnection();
// JMD - this is a better way to do it that doesn't override the default SSL factory.
if (connection instanceof HttpsURLConnection)
{
HttpsURLConnection conHttps = (HttpsURLConnection) connection;
// Set up a Trust all manager
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager()
{
public java.security.cert.X509Certificate[] getAcceptedIssuers()
{
return null;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType)
{
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType)
{
}
} };
// Get a new SSL context
SSLContext sc = SSLContext.getInstance("TLSv1.2");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
// Set our connection to use this SSL context, with the "Trust all" manager in place.
conHttps.setSSLSocketFactory(sc.getSocketFactory());
// Also force it to trust all hosts
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
// and set the hostname verifier.
conHttps.setHostnameVerifier(allHostsValid);
}
InputStream stream = connection.getInputStream();
