Password Encryption Decryption in Java with Java 9+ modules

Java AES Encryption and Decryption

Advanced Encryption Standard is one of the most popular encryption algorithms. It is an asymmetric encryption algorithm and more secure.

AES is generally used for securing sensitive information so we can say that is enough secure.

Before AES most of the organizations used the DES( Data Encryption Standard) algorithm which is not secure and most of the organizations considered that highly insecure.

Feature of AES
AES is the replacement for DES. Some features of AES are listed below:
  • Symmetric key symmetric block cipher
  • 128-bit data, 128/192/256-bit keys
  • Stronger and faster than Triple-DES
  • Provide full specification and design details
  • Software implementable in C and Java

Below is the utility class which will be used for encryption and decryption in Java applications.


Java Modules

Starting with Java 9 a new concept was introduced: modules. Java modules represent a more powerful mechanism to organize and aggregate packages.

A Java module is a way to group packages and configure more granulated access to package contents. A Java module is a uniquely named, reusable group of packages and resources (e.g., XML files and other types of non-Java files) described by a file named module-info.java, located at the root of the source directory.

Debug Java Stream in Intellij Idea

-

Stream is a very powerful feature. it allows you to take full advantage of modern multi-core architectures and lets you process data in a declarative way.  Unfortunately stream API may sometimes be difficult to debug. This happens because they require you to insert additional breakpoints and thoroughly analyze each transformation inside the stream.  IntelliJ IDEA provides a solution to this by letting you visualize what is going on in Java Stream operations. Just install plugin called “Java Stream Debugger”. Once you have enabled this plugin you can simply debug your code. This plugin will bring a trace icon (Trace Current Stream Chain button).   Trace Current Stream Chain button Once you click on that icon you get the visualization of your stream pipeline.  For every stream operation, we have got a dedicated tab. you have to switch to the relevant tab to understand what it is doing.

Creating Efficient Docker Images with Spring Boot 2.3

Spring Boot 2.3 brings with it some interesting new features that can help you package up your Spring Boot application into Docker images. The first problem with common docker techniques is that the jar file is not unpacked. There’s always a certain amount of overhead when running a fat jar, and in a containerized environment this can be noticeable. It’s generally best to unpack your jar and run in an exploded form. The second issue with the file is that it isn’t very efficient if you frequently update your application. Docker images are built in layers, and in this case your application and all its dependencies are put into a single layer. Since you probably recompile your code more often than you upgrade the version of Spring Boot you use, it’s often better to separate things a bit more. If you put jar files in the layer before your application classes, Docker often only needs to change the very bottom layer and can pick others up from its cache. Two new features are introduced in Sp...

CRUD Goes Even Easier With JPABuddy

Image
Create, Read, Update and Delete are the four basic operations of persistence storage. We can say these operations collectively as an acronym CRUD. These operations can be implemented in JPA. JPA is a standard for ORM. It is an API layer that maps Java objects to the database tables.  ORM stands for Object Relational Mapping. It converts data between incompatible type systems in object-oriented programming languages.  JPA Buddy is an IntelliJ IDEA plugin that helps developers work efficiently. JPA Buddy is a tool that is supposed to become your faithful coding assistant for projects with JPA and everything related. It is an advanced plugin for IntelliJ IDEA intended to simplify and accelerate everything related to JPA and surrounding mainstream technology. In fact, you can develop an entire CRUD application or a simple microservice by spending nearly zero time writing boilerplate code. The video demonstrates the features of JPA Buddy by creating a simple CRUD application from ...
