Sure.

The certificate objects can be created by an instance of [CertificateFactory][1] - in particular, one configured to create X509 certificates.  This can be created like so:

    CertificateFactory certFactory = CertificateFactory.getInstance(&quot;X.509&quot;);

Then you need to pass it an InputStream containing the bytes of the certificate.  This can be achieved by wrapping your byte array in a [ByteArrayInputStream][2]:

    InputStream in = new ByteArrayInputStream(bytes);
    X509Certificate cert = (X509Certificate)certFactory.generateCertificate(in);


  [1]: http://docs.oracle.com/javase/7/docs/api/java/security/cert/CertificateFactory.html
  [2]: http://docs.oracle.com/javase/7/docs/api/java/io/ByteArrayInputStream.html

You can do something like:


    X509Certificate certificate = signature.getKeyInfo().getX509Datas().get(0).getX509Certificates().get(0);
 
    String lexicalXSDBase64Binary = certificate.getValue();
    byte[] decoded = DatatypeConverter.parseBase64Binary(lexicalXSDBase64Binary);

            
    CertificateFactory certFactory = CertificateFactory.getInstance(&quot;X.509&quot;);
    Certificate cert = certFactory.generateCertificate(new ByteArrayInputStream(decoded));

    InputStream stream = null;
    byte[] bencoded = javax.xml.bind.DatatypeConverter.parseBase64Binary(x509CertificateStr);

    try {
        CertificateFactory certFactory = CertificateFactory.getInstance(&quot;X.509&quot;);
        cert = (X509Certificate) certFactory.generateCertificate(stream);

    } catch (java.security.cert.CertificateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

How can I configure Logback to suppress all of its output to the console (standard output)?  In particular, I wish to suppress (or redirect) Logback&#39;s own log messages such as the following:

    16:50:25,814 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]
    16:50:25,814 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/opt/dap/domains/ap0491/uat1/domain/instance-config/logback.xml]

I need to disable all logging to standard output because our production environment disallows applications from printing any messages to standard output.

Note I&#39;m using Logback 0.9.21, SLF4J 1.6.0, and our application runs in WebLogic 10.3.2.

I have numbers like 1100, 1002, 1022 etc. I would like to have the individual digits, for example for the first number 1100 I want to have 1, 1, 0, 0.

How can I get it in Java?

I know this question is asked quite a bit, and obviously you can&#39;t parse any arbitrary date.  However, I find that the python-dateutil library is able to parse every date I throw at it, all while requiring absolutely zero effort in figuring out a date format string.  Joda time is always sold as being a great Java date parser, but it still requires you to decide what format your date is in before you pick a Format (or create your own).  You can&#39;t just call DateFormatter.parse(mydate) and magically get a Date object back.

For example, the date &quot;Wed Mar 04 05:09:06 GMT-06:00 2009&quot; is properly parsed with python-dateutil:

    import dateutil.parser
    print dateutil.parser.parse(&#39;Wed Mar 04 05:09:06 GMT-06:00 2009&#39;)

but the following Joda time call doesn&#39;t work:

        String date = &quot;Wed Mar 04 05:09:06 GMT-06:00 2009&quot;;
        DateTimeFormatter fmt = ISODateTimeFormat.dateTime();
        DateTime dt = fmt.parseDateTime(date);
        System.out.println(date);

And creating your own DateTimeFormatter defeats the purpose, since that seems to be the same as using SimpleDateFormatter with the correct format string.

Is there a comparable way to parse a date in Java, like python-dateutil?  I don&#39;t care about errors, I just want it to mostly perfect.

There&#39;s an Entity Class &quot;A&quot;. Class A might have children of the same type &quot;A&quot;. Also &quot;A&quot; should hold it&#39;s parent if it is a child.  

Is this possible? If so how should I map the relations in the Entity class?
[&quot;A&quot; has an id column.]

JPA: How to have one-to-many relation of the same Entity type

I am wondering if it is possible using annotations to persist the `attributes` map in the following class using JPA2

    public class Example {
        long id;
        // ....
        Map&lt;String, String&gt; attributes = new HashMap&lt;String, String&gt;();
        // ....
    }

As we already have a pre existing production database, so ideally the values of `attributes`  could map to the following existing table:

    create table example_attributes {
        example_id bigint,
        name varchar(100),
        value varchar(100));



Storing a Map&lt;String,String&gt; using JPA

When you have to loop through a collection and make a string of each data separated by a delimiter, you always end up with an extra delimiter at the end, e.g.

    for (String serverId : serverIds) {
      sb.append(serverId);
       sb.append(&quot;,&quot;);
    }

Gives something like : **serverId_1, serverId_2, serverId_3,**

I would like to delete the last character in the StringBuilder (without converting it because I still need it after this loop).

I&#39;m having a problem when I use the method `X509Store.Certificates.Find`

    public static X509Certificate2 FromStore(StoreName storeName, 
              StoreLocation storeLocation, X509FindType findType, string findValue)
    {
        X509Store store = new X509Store(storeName, storeLocation);
        store.Open(OpenFlags.ReadOnly);
        try
        {
            //findValue = &quot;7a6fa503ab57b81d6318a51ca265e739a51ce660&quot;
            var results = store.Certificates.Find(findType, findValue, true);

            return results[0];                
        }
        finally
        {
            store.Close();
        }
    }
In this case the Find Method returns 0 results (`results.Count == 0`), but if I put the findValue as constant the method find the certificate.

    public static X509Certificate2 FromStore(StoreName storeName, 
               StoreLocation storeLocation, X509FindType findType, string findValue)
    {
        X509Store store = new X509Store(storeName, storeLocation);
        store.Open(OpenFlags.ReadOnly);
        try
        {         
            //findValue= &quot;7a6fa503ab57b81d6318a51ca265e739a51ce660&quot;
            var results = store.Certificates.Find(findType, 
                                  &quot;7a6fa503ab57b81d6318a51ca265e739a51ce660&quot;, true);
            return results[0];
        }
        finally
        {
            store.Close();
        }
    }

Problems with X509Store Certificates.Find FindByThumbprint

I&#39;m using *openssl* to create self-signed certs. I&#39;m getting this error with the certs I generated:

&gt; javax.net.ssl.SSLHandshakeException:
&gt; java.security.cert.CertificateException: No subject alternative names
&gt; present

&lt;br&gt;
Does anyone know how to specify &quot;Subject alternative name&quot; while creating a cert?
This is how I&#39;m generating a keystore:
       
    sudo $JAVA_HOME/bin/keytool -genkey -dname &quot;CN=192.168.x.xxx, OU=I, O=I, L=T, ST=On, C=CA&quot; -alias tomcat -validity 3650 -keyalg RSA -keystore /root/.keystore -keypass abcd -storepass abcd

To generate a key:

     openssl s_client -connect 192.168.x.xxx:8443 2&gt;/dev/null

Please help! Thanks!

How to add subject alernative name to ssl certs?

I have an X.509 certificate which has the following 2 timestamps:

    [&#39;validFrom&#39;] = String(13) &quot;120314165227Z&quot;
    [&#39;validTo&#39;]   = String(13) &quot;130314165227Z&quot;

What does the postfix character &#39;Z&#39; mean. Does it specify the timezone?

What does the &#39;Z&#39; mean in Unix timestamp &#39;120314170138Z&#39;?

    //cert is an EF Entity and 
    //    cert.CertificatePKCS12 is a byte[] with the certificate.

    var certificate = new X509Certificate(cert.CertificatePKCS12, &quot;SomePassword&quot;);

When loading a certificate from our database, on our staging server (Windows 2008 R2/IIS7.5) we get this exception:

    System.Security.Cryptography.CryptographicException: An internal error occurred.
    
       at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr)
       at System.Security.Cryptography.X509Certificates.X509Utils._LoadCertFromBlob(Byte[] rawData, IntPtr password, UInt32 dwFlags, Boolean persistKeySet, SafeCertContextHandle&amp; pCertCtx)
       at System.Security.Cryptography.X509Certificates.X509Certificate.LoadCertificateFromBlob(Byte[] rawData, Object password, X509KeyStorageFlags keyStorageFlags)

**NOTE:** This issue does not happen locally (Windows 7/Casini).

Any insight is greatly appreciated.

X509Certificate Constructor Exception

I&#39;m adding HTTPS support to an embedded Linux device. I have tried to generate a self-signed certificate with these steps:

    openssl req -new &gt; cert.csr
    openssl rsa -in privkey.pem -out key.pem
    openssl x509 -in cert.csr -out cert.pem -req -signkey key.pem -days 1001
    cat key.pem&gt;&gt;cert.pem

This works, but I get some errors with, for example, Google Chrome:

&gt; This is probably not the site you are looking for!&lt;br&gt;
&gt; The site&#39;s security certificate is not trusted!

Am I missing something? Is this the correct way to build a self-signed certificate?
