&#39;cacerts&#39; is a truststore. A trust store is used to authenticate peers. A keystore is used to authenticate yourself.

cacerts is where Java stores public certificates of root CAs. Java uses cacerts to authenticate the servers.

Keystore is where Java stores the private keys of the clients so that it can share it to the server when the server requests client authentication.


***Cacerts*** are details of trusted signing authorities who can issue certs. This what most of the browsers have due to which certs determined to be authentic.
 
***Keystore*** has your service related certs to authenticate clients. 

Check your JAVA_HOME path. As systems looks for a java.policy file which is located in `JAVA_HOME/jre/lib/security`. Your JAVA_HOME should always be `../JAVA/JDK`.


We are beginning to use the code review functionality built-in to VS 2012 and VS 2013 preview. Requesting the review and adding comments seem pretty straightforward. If someone adds comments requesting the code to be changed, then how does the requester make these changes and show them?

So the process would flow like this:

1. Person 1 requests a code review.
2. Person 2 adds comments and selects &quot;Needs Work.&quot;
3. Person 1 makes the necessary changes.

How does Person 1 now show these changes to Person 2? You can add comments and send them, but the files don&#39;t change. I&#39;m assuming the files are from the changeset created when the original review was requested. Should Person 1 close this review, and request a second review?

Creating a second review doesn&#39;t seem optimal, because you lose the history of your conversation of why you were making the changes.

There are ton of websites showing how to use the basic functionality of the code reviews, but are there any sites that show the best practices? For instance, who should be clicking the check boxes next to files?

I finally released my project to the production level and suddenly I have some issues I never had to deal with in the development phase.

When the users posts some actions, I sometimes get the following error.

    Traceback (most recent call last):
    
      File &quot;/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py&quot;, line 111, in get_response
        response = callback(request, *callback_args, **callback_kwargs)
    
      File &quot;home/ubuntu/server/opineer/comments/views.py&quot;, line 103, in comment_expand

        % self.model._meta.object_name)
    
    DoesNotExist: Comment matching query does not exist


What really frustrates me is that the project works fine in the local environment and furthermore, the matching query object DOES exist in the Database.

Now I am suspecting that the user is accessing the Database when it&#39;s reserved to other users, but there&#39;s no way to prove my argument nor I have any solution to it.

Does anybody had this kind of issue before? Any suggestions on how to resolve this issue?


Thank you very much for your help in advance.


EDIT: I have manually queried the database using the same information retrieved from the server error email I received. I was able to hit the entry without any issue. Furthermore, it seems like the exact same behavior the user performed does not raise any issue most of the time, but rather in some (which is yet unknown) cases. In conclusion, it definitely is not an issue with the missing entry in the database.

What&#39;s the difference between the two, cacerts and keystore?

If I use the definition found in these links, [cacerts][1] and [keystore][2], it seems that they&#39;re a collection of certificates, but in context of a (Java) distributed system. Which one is used to authenticate during an SSL connection? Both or just one of them or alternate?

I&#39;m very new to design patterns and am having trouble with the difference between [fluent interfaces](http://en.wikipedia.org/wiki/Fluent_interface) and the Builder pattern.

I understand the concept of fluent interfaces. But the builder pattern is a little confusing. I cannot understand the use of a Director in the Builder pattern.  

Can I use the Builder pattern and Fluent Interface together? If so, then how should I do so with a Director and a concrete builder?

My question is **not** about advantages of builder pattern. But the aim of this question is to know the relation between builder pattern and fluent interface.

I have two objects of **DateTime**, which need to find the **duration of their difference**, 

I have the following code but not sure how to continue it to get to the expected results as following:

**Example**:

          11/03/14 09:30:58
          11/03/14 09:33:43
          elapsed time is 02 minutes and 45 seconds
          -----------------------------------------------------
          11/03/14 09:30:58 
          11/03/15 09:30:58
          elapsed time is a day

          11/03/16 09:30:58
          elapsed time is two days
          -----------------------------------------------------
          11/03/14 09:30:58 
          11/03/16 09:35:58
          elapsed time is two days and 05 minutes
          

**Code**: 

        String dateStart = &quot;11/03/14 09:29:58&quot;;
        String dateStop = &quot;11/03/14 09:33:43&quot;;

        // Get msec from each, and subtract.
        long diff = d2.getTime() - d1.getTime();
        long diffSeconds = diff / 1000 % 60;

        System.out.println(&quot;Time in hours: &quot; + diffHours + &quot; hours.&quot;);

FIXED: this is a [known bug][1] in maven-compiler-plugin 3.1

I am converting an ant-based build of a 1000+ java-sources project to maven. So far so good, but every time launch `mvn compile` it recompiles everything (instead of reusing old classes)

Using `mvn -X compile` reports that

    [DEBUG] Stale source detected: /project_path/src/main/java/package_path/AFile1.java
    [DEBUG] Stale source detected: /project_path/src/main/java/package_path/AFile2.java
    ...
(**only for files in a certain package**, which is possibly unreferenced from the rest of the code; not my sources, I am just trying to mavenize the build)

Compilation does not fail, and classes with updated timestamps are being generated at

    /project_path/target/classes/package_path/AFile1.class
    /project_path/target/classes/package_path/AFile2.class
    ...

However, when looking at timestamps, the java files have not changed since yesterday, and the class files are current. Why are these sources determined to be stale? How can I debug this issue?.

It is a drag to have to recompile 1k+ files even when no changes have occurred...

I want to draw circle by canvas. Here is my code:

[MyActivity.java]:

    public class MyActivity extends Activity 
    {
     public void onCreate(Bundle savedInstanceState) 
       {
          ...
          setContentView(new View(this,w,h));
       }
            
    }

[View.java]:

    public class View extends SurfaceView
    {
        public View(Context context, int w, int h)
        {
            super(context);
            Canvas grid = new Canvas(Bitmap.createBitmap(h,w, Bitmap.Config.ARGB_8888));
            grid. drawColor(Color.WHITE);
            Paint paint = new Paint();
            paint.setStyle(Paint.Style.FILL);
            grid.drawCircle(w/2, h/2 , w/2, paint);
        }
    }

So I have just black screen without circle.
Why it does not work? How to fix it?

I have noticed the following code is redirecting the User to a URL inside the project, 

    @RequestMapping(method = RequestMethod.POST)
    public String processForm(HttpServletRequest request, LoginForm loginForm, 
                              BindingResult result, ModelMap model) 
    {
        String redirectUrl = &quot;yahoo.com&quot;;
        return &quot;redirect:&quot; + redirectUrl;
    }

whereas, the following is redirecting properly as intended, but requires http:// or https://

    @RequestMapping(method = RequestMethod.POST)
        public String processForm(HttpServletRequest request, LoginForm loginForm, 
                                  BindingResult result, ModelMap model) 
        {
            String redirectUrl = &quot;http://www.yahoo.com&quot;;
            return &quot;redirect:&quot; + redirectUrl;
        }

I want the redirect to always redirect to the URL specified, whether it has a valid protocol in it or not and do not want to redirect to a view. How can I do that?

Thanks,

What happens if the old certificate expires? Will users be available do download my app with old certificate, or will Apple remove my app until the new certificate is provided?

I have a Java web service client, which consumes a web service via HTTPS.

	import javax.xml.ws.Service;

	@WebServiceClient(name = &quot;ISomeService&quot;, targetNamespace = &quot;http://tempuri.org/&quot;, wsdlLocation = &quot;...&quot;)
	public class ISomeService
		extends Service
	{

		public ISomeService() {
			super(__getWsdlLocation(), ISOMESERVICE_QNAME);
		}


When I connect to the service URL (`https://AAA.BBB.CCC.DDD:9443/ISomeService` ), I get the exception `java.security.cert.CertificateException: No subject alternative names present`.

To fix it, I first ran `openssl s_client -showcerts -connect AAA.BBB.CCC.DDD:9443  &gt; certs.txt` and got following content in file `certs.txt`:

	CONNECTED(00000003)

	---

AFAIK, now I need to

  1. extract the part of `certs.txt` between `-----BEGIN CERTIFICATE-----` and `-----END CERTIFICATE-----`,
  1. modify it so that the certificate name is equal to `AAA.BBB.CCC.DDD` and
  1. then import the result using `keytool -importcert -file fileWithModifiedCertificate` (where `fileWithModifiedCertificate` is the result of operations 1 and 2).

Is this correct?

If so, how exactly can I make the certificate from step 1 work with IP-based adddress (`AAA.BBB.CCC.DDD`) ?

**Update 1 (23.10.2013 15:37 MSK):** In an answer to a [similar question][1], I read the following:

&gt; If you&#39;re not in control of that server, use its host name (provided
&gt; that there is at least a CN matching that host name in the existing
&gt; cert).

What exactly does &quot;use&quot; mean?

I&#39;ve created a chain hierarchy like this.

    root-ca ==&gt; signing-ca ==&gt; subordinate-ca ==&gt; server

It is mentioned to create chain bundle, the lowest should go first.

    $ cat server.crt subordinate-ca.crt signing-ca.crt &gt; server.pem

But verification fails.

    $ openssl verify -CAfile root-ca.crt server.pem
    error 20 at 0 depth lookup:unable to get local issuer certificate

However, if I change the order it seems to work.

    $ cat signing-ca.crt subordinate-ca.crt server.crt &gt; server.pem
    $ openssl verify -CAfile root-ca.crt server.pem
    server.pem: OK

So what would be the error here? 


The chain after &quot;cat&quot; looks like below.

    -----BEGIN CERTIFICATE-----
    ...
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    ...
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    ...
    -----END CERTIFICATE-----

More info: According to &quot;http://www.herongyang.com/crypto/openssl_verify_2.html&quot;, I perform the following test which works.

    $ cat signing-ca.crt subordinate-ca.crt &gt; inter.crt
    $ openssl verify -CAfile root-ca.crt -untrusted inter.crt server.crt
    server.crt: OK

Does that mean all the links are good?


OK, I finally discover that this cannot be done through OpenSSL command line (or at least easily). http://openssl.6102.n7.nabble.com/check-certificate-chain-in-a-pem-file-td43871.html

    sun.security.provider.certpath.SunCertPathBuilderException: unable to find
    valid certification path to requested target
    .
    .
    Caused by: 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

Searching on how to resolve this exception I have come across the term `Keystore` which I do not understand. What is Keystore in simple terms? How it is related to SSL?


What is Keystore?

Using some batch file, I want to add the untrusted self signed certificate within Java Keystore.

**Command is**

    %JAVA_HOME%/bin/keytool -import -v -trustcacerts -alias server-alias
    -file server.cer -keystore cacerts.jks -keypass changeit -storepass changeit

After running above command, the screen promts for Trust of certificate using Y/N.

    Trust this certificate? [no]:

But I don&#39;t want to provide Y/N here.

Is there a way to complete the import using a single command or some additional import switch if any?


Add Self Signed Certificate without promting Yes/No from User

I&#39;m writing an application in Java which connects to two web servers via HTTPS. One got a certificate trusted via the default chain of trust, the other uses a self signed certificate. Of course, connecting to the first server worked out of the box, whereas connecting to the server with the self signed certificate did not work until I created a trustStore with the certificate from that server. However, the connection to the by default trusted server does not work any more, because apparently the default trustStore gets to be ignored once I created my own.

One solution I found was to add the certificates from the default trustStore to my own. However, I don&#39;t like this solution, because it requires me to keep managing that trustStore. (I cannot assume these certificates remain static in the foreseeable future, right?)

Apart from that I found two 5 year old threads with a similar problem:

https://stackoverflow.com/questions/1793979/registering-multiple-keystores-in-jvm

https://stackoverflow.com/questions/1788031/how-can-i-have-multiple-ssl-certificates-for-a-java-server

They both go deep into the Java SSL infrastructure. I was hoping that by now there is a more convenient solution which I can explain easily in a security review of my code.

Using a custom truststore in java as well as the default one

I am developing a Java application that queries a REST API on a remote server over HTTP. For security reasons this communication should be switched to HTTPS.

Now that [Let&#39;s Encrypt](https://letsencrypt.org/) started their public beta, I&#39;d like to know if Java currently works (or is confirmed to be working in the future) with their certificates by default.

Let&#39;s Encrypt got their intermediate [cross-signed by IdenTrust](https://letsencrypt.org/certificates/#cross-signing), which should be good news. However, I cannot find any of these two in the output of this command:

    keytool -keystore &quot;..\lib\security\cacerts&quot; -storepass changeit -list

I know that trusted CAs can be added manually on each machine, but since my application should be free to download and executable without any further configuration, I am looking for solutions that work &quot;out of the box&quot;. Do you have good news for me?
