In other languages, programmers allocate their own memory and often fail to do it correctly, causing buffer overflows, etc. Java platform has APIs to facilitate the creation, storage, and validation of digital certificates: Java has a built-in trust-store called cacerts that contains certificates for well known CAs. Not even remotely quick. This allows us to write secure code, as well as benefit from many implicit security features: This is not a complete list of security features that Java provides, but it's good enough to give us some assurance! A mutually authenticated SSL connection requires us to do two things: We rarely have to do this programmatically and normally pass system parameters to Java at runtime: Authentication is the process of verifying the presented identity of a user or machine based on additional data like password, token, or a variety of other credentials available today. For instance if any unauthorized method is trying to access private variable then at compile time JVM fetches error. Java provides APIs to secure network communication with encryption, message integrity, and both client and server authentication: Let's now see how we can open a secure connection with other parties in Java using SSLSocket: Here, we are using SSLSocketFactory to create SSLSocket. It controls the socket connections also. Java API supports generating and validating XML signatures as per the recommended guidelines. How to implement Java program to check Leap Year? Also, we have to provide an instance of CallbackHandler, using the LoginModule that interacts with the user for details like username and password. For running the java program, a computer needs JRE.
