I'm building two java applications which have to communicate using SSL two way authentication, I used instructions from here to create client and server certificates.
then I built a webService in the server application like this:
@RequestMapping(value="/testssl", method = RequestMethod.POST, produces="application/json", consumes="application/json")
@ResponseBody
public String testSSl(@RequestBody String name) {
return = successfully tested;
}
and I edited tomcat server.xml file to enable SSL like this:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="true" sslProtocol="TLS"
keystoreFile="keyStore/server.jks"
keystorePass="server123" />
and put server.jks in Tomcat/Jenkins-Tomcat/keystore/server.jks
then I built the client application to invoke this web service through SSL using spring RestTemplate like this:
Properties props = new Properties();
props.put("javax.net.ssl.trustStore", "D:\\test\\server.jks");
props.put("javax.net.ssl.trustStoreType", "jks");
props.put("javax.net.ssl.trustStorePassword", "server123");
props.put("javax.net.ssl.keyStore", "D:\\test\\client.jks");
props.put("javax.net.ssl.keyStoreType", "jks");
props.put("javax.net.ssl.keyStorePassword", "client123");
props.put("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
props.put("ws.ssl.loose.disableHostnameVerification", "true");
System.setProperties(props);
SSLContext sslcontext = SSLContexts.createDefault();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext,
new String[] { "TLSv1" }, null, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext.getSocketFactory());
CloseableHttpClient httpClient = HttpClientBuilder.create()
.setSSLSocketFactory(sslsf).build();
org.springframework.http.client.HttpComponentsClientHttpRequestFactory cc = new HttpComponentsClientHttpRequestFactory(httpClient);
RestTemplate rest = new RestTemplate(cc);
String resp = rest.postForObject("https://10.141.0.77:8443/Monim/testssl", "monim", String.class);
System.err.println(resp);
but when I run this application I get unable to find valid certification path to requested target exception. I tried to create the certificates again but the error still present.
when I request the url from firefox browser I get An error occurred during a connection to 10.141.0.77:8443. SSL peer cannot verify your certificate. (Error code: ssl_error_bad_cert_alert)
and when using chrome to access the url I get
Error code: ERR_BAD_SSL_CLIENT_AUTH_CERT
here is the stacktrace of the client application
org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://10.141.0.77:8443/Monim/testssl":sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

how to fix this error. thanks
after spending a long time to make this work, the solution is as follows:
first when setting the properties using System.put("key", "value") I noticed after many tries it is not setting the KeyStore value it is does not appear in the ssl log , also tried to set the properties as parameters in the tomcat configuration using -Djavax.net.ssl.keyStore="" this also didn't work.
so I read the KeyStore from an InputStream like this:
KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
FileInputStream io = new FileInputStream("path/to/jks/file.jks");
try{
keystore.load(io, "pass".toCharArray());
} finally {
io.close();
}
and use the same previous code to read the TrustStore like :
KeyStore trustStore= KeyStore.getInstance(KeyStore.getDefaultType());
FileInputStream stream = new FileInputStream("path/to/truststore/file.jks");
try{
keystore.load(stream, "trusted".toCharArray());
} finally {
stream.close();
}
after that define the SSLContext :
SSLContext sslcontext = SSLContexts.custom()
.loadKeyMaterial(keystore, "keyPassword".toCharArray())
.loadTrustMaterial(truststore, new TrustSelfSignedStrategy())
.build();
loadKeyMaterial used to load the keyStore it takes the password of your privateKey "keyPassword" as a parameter, so you must protect the private key using a password, when I tried to use a plain private key not encrypted "protected" with a password, I get exception which says: java.security.UnrecoverableKeyException: Cannot recover key, by default this is the same as the keystore password unless you changed it.
then create the SSLConnectionSocketFactory and pass it as a parameter to the HttpClient ..
this worked for me :)
