javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca
提问by Stine
I have to connect to a server via SSL dual authentication. I have added my own private key plus certificate to a keystore.jksand the self signed certificate of the server to a truststore.jks, both files are copied to /usr/share/tomcat7. The socket factory used by my code is delivered by the following provider:
我必须通过 SSL 双重身份验证连接到服务器。我已将自己的私钥和证书添加到keystore.jks并将服务器的自签名证书添加到truststore.jks，这两个文件都被复制到 /usr/share/tomcat7。我的代码使用的套接字工厂由以下提供程序提供：
@Singleton
public static class SecureSSLSocketFactoryProvider implements Provider<SSLSocketFactory> {
private SSLSocketFactory sslSocketFactory;
public SecureSSLSocketFactoryProvider() throws RuntimeException {
try {
final KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
final InputStream trustStoreFile = new FileInputStream("/usr/share/tomcat7/truststore.jks");
trustStore.load(trustStoreFile, "changeit".toCharArray());
final TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(trustStore);
final KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
final InputStream keyStoreFile = new FileInputStream("/usr/share/tomcat7/keystore.jks");
keyStore.load(keyStoreFile, "changeit".toCharArray());
final KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, "changeit".toCharArray());
final SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), null);
this.sslSocketFactory = sslContext.getSocketFactory();
} catch (final KeyStoreException e) {
Log.error("Key store exception: {}", e.getMessage(), e);
} catch (final CertificateException e) {
Log.error("Certificate exception: {}", e.getMessage(), e);
} catch (final UnrecoverableKeyException e) {
Log.error("Unrecoverable key exception: {}", e.getMessage(), e);
} catch (final NoSuchAlgorithmException e) {
Log.error("No such algorithm exception: {}", e.getMessage(), e);
} catch (final KeyManagementException e) {
Log.error("Key management exception: {}", e.getMessage(), e);
} catch (final IOException e) {
Log.error("IO exception: {}", e.getMessage(), e);
}
}
@Override
public SSLSocketFactory get() {
return sslSocketFactory;
}
}
When I try to connect to an endpoint on the server I get the following exception though:
当我尝试连接到服务器上的端点时，我收到以下异常：

Any idea what I have missed here?
知道我在这里错过了什么吗？

If you get an alert unknown_caback from the server, then the server did not like the certificate you've send as the client certificate, because it is not signed by a CA which is trusted by the server for client certificates.
如果您unknown_ca从服务器收到警报，则服务器不喜欢您作为客户端证书发送的证书，因为它不是由服务器信任的客户端证书的 CA 签署的。
