Mercurial is a fast, lightweight Source Control Management system designed for efficient handling of very large distributed projects. It is mainly implemented using the Python programming language. It is supported on Windows and Unix-like systems, such as Mac OS X and Linux. All of Mercurial's operations are invoked as arguments to its driver program hg, a reference to the chemical symbol of the element mercury. Mercurial's major design goals include high performance and scalability, decentralized, fully distributed collaborative development, robust handling of both plain text and binary files, and advanced branching and merging capabilities, while remaining conceptually simple.  How you can benefit from Mercurial It is fast and powerful, It efficiently handles projects of any size and kind. Every clone contains the whole project history, so most actions are local, fast and convenient. Mercurial supports a multitude of workflows and you can easily enhance its fun...

In my previous blog , I have explained how can you create self signed certificate using bouncy castle API and how to import it into keystore. This tutorial will explain how to read existing certificate file using java.security.cert.CertificateFactory class. import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.security.KeyStore; import java.security.PublicKey; import java.security.cert.Certificate; import java.security.cert.CertificateFactory; /**  * Reads the certificate and import into Java keystore.  *  * @author abdul  *  */ public class ReadCertificateFile {      /**      * @param args      * @throws Exception      */     public static void main(String[] args) throws Exception {         ReadCertificateFile readCertificateFile = new ReadCertificateFile();   ...
