An alternative to using `keytool`, you can use the command

    openssl x509 -in certificate.pem -text

This should work for any x509 .pem file provided you have [`openssl`][1] installed.


  [1]: https://www.openssl.org/docs/manmaster/man1/openssl-x509.html#Display-Options

Use the [`-printcert`][1] command like this:

    keytool -printcert -file certificate.pem

I am trying to test [OAuth][1] buttons, but they all (Facebook, Twitter, LinkedIn) come back with errors that seem to signal that I can not test or use them from a *local* URL.

How do people usually work in development with OAuth stuff if they all seem to require a *non-dev* and *non-local* connections environments?

How do I prevent a form from submitting using jquery?

I tried everything - see 3 different options I tried below, but it all won&#39;t work: 

        $(document).ready(function() { 
        
                //option A
                $(&quot;#form&quot;).submit(function(e){
                    e.preventDefault();
                });

                //option B
                $(&quot;#form&quot;).submit(function(e){
                    stopEvent(e);
                });

                //option C
                $(&quot;#form&quot;).submit(function(){
                    return false;
                });
        });

What could be wrong?


Update - here is my html:

        &lt;form id=&quot;form&quot; class=&quot;form&quot; action=&quot;page2.php&quot; method=&quot;post&quot;&gt; 
           &lt;!-- tags in the form --&gt;
           &lt;p class=&quot;class2&quot;&gt;
               &lt;input type=&quot;submit&quot; value=&quot;Okay!&quot; /&gt; 
           &lt;/p&gt;
        &lt;/form&gt;

Is there anything wrong here?

Using JQuery - preventing form from submitting

I am using Java `keytool`. I have exported a self-signed `.pem` certificate from my keystore. Is there a command to view the certificate details directly from the `.pem` file (not of the certificate in the keystore)?

How to view the contents of a .pem certificate?

<p>I am using Java <code>keytool</code>. I have exported a self-signed <code>.pem</code> certificate from my keystore. Is there a command to view the certificate details directly from the <code>.pem</code> file (not of the certificate in the keystore)?</p>


I&#39;m trying to connect a Java Web API via HTTPS; however, an exception is thrown:

    javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException

I followed these steps which I learned from online keytool &amp; SSL cert tutorials:

1. I copied the HTTPS URL into the browser, downloaded the SSL certificates &amp; Installed them in the browser using Internet Explorer.

2. Exported the certificates to a path on my computer, the certificates were saved as `.cer`

3. Used the keytool&#39;s import option. The command below executed without any errors.

        keytool -import -alias downloadedCertAlias -keystore C:\path\to\my\keystore\cacerts.file -file C:\path\of\exportedCert.cer


4. I was prompted for a password at the command prompt, which I entered then I was authenticated. 

5. The `cmd` window printed some certificate data &amp; signatures and I was prompted with the question:  

    &gt; Trust this certificate?

 I answered yes.

6. The cmd prompt displayed 
  
    &gt; Certificate was added to keystore

  However after that message, another exception was displayed:

        keytool error: java.io.FileNotFoundException: C:\Program files\...\cacerts &lt;Access Denied&gt;

Finally when I checked the keystore , the SSL certificate was not added and my application gives the same exception I was getting earlier when trying to connect:

    (javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException)

Java Keytool error after importing certificate , &quot;keytool error: java.io.FileNotFoundException &amp; Access Denied&quot;

I do want to import a self signed certificate into Java so any Java application that will try to establish a SSL connection will trust this certificate.

So far, I managed to import it in
    
    keytool -import -trustcacerts -noprompt -storepass changeit -alias $REMHOST -file $REMHOST.pem
    keytool -import -trustcacerts -noprompt -keystore cacerts -storepass changeit -alias $REMHOST -file $REMHOST.pem

Still, when I try to run [`HTTPSClient.class`](http://adywicaksono.wordpress.com/2007/07/15/ssl-connection-with-java/) I still get:

&lt;pre&gt;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&lt;/pre&gt;


How to properly import a selfsigned certificate into Java keystore that is available to all Java applications by default?

I wish to generate an application signature for my app which will later be integrated with Facebook. In one of Facebook&#39;s tutorials, I found this command:

    keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

In the tutorial, it says that by running this cmd, my process of generating the signature will start.

However, this command gives an error:

    openssl is not recognized as an internal or external command

How can I get rid of this?

I am trying to import a certificate and a key file into the keystore but I&#39;m unable to do that.

How can I create a keystore by importing both an existing certificate (abc.crt) and abc.key files?

How can I create keystore from an existing certificate (abc.crt) and abc.key files?

I have a jks keystore with no password.  When I run the command

    keytool -list -keystore mykeystore.jks

And it prompts me for the keystore password, I simply hit &#39;enter&#39;.

Please note that the keystore password IS NOT the default java password of &#39;changeit&#39;. It is blank

When I try to run

    keytool -storepasswd -keystore mykeystore.jks

to change the password to a non blank string. It firsts prompts me for the current password. Simply hitting enter since it is blank says

    keytool -storepasswd -keystore mykeystore.jks
    Enter keystore password:
    Keystore password is too short - must be at least 6 characters 

Just to confirm with everyone that the password is not &#39;changeit&#39;

    keytool -storepasswd -keystore mykeystore.jks
    Enter keystore password:  changeit
    keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

Any idea how I can change the keystore password if the existing password is blank?
