Welcome to our tech tour! You are a genuine explorer👉 Today we are going to show you how to configure Visual Studio Code for Kotlin development.   Why Visual Studio Code?   Visual Studio Code features a lightning expeditious source code editor, perfect for our development activities. With support for hundreds of languages, VS Code avails us instantly productive with syntax highlighting, bracket-matching, auto-indentation, box-cull, snippets, and more. Visual Studio Code fortifies macOS, Linux, and Windows - so we can hit the ground running, no matter the platform.     A quick overview of Kotlin,   Kotlin is a new open-source programming language targeting the Java platform. Kotlin is concise, safe, pragmatic, and fixated on interoperability with Java code. It can be used virtually everywhere Java is utilized today: for server-side development, Android apps, and much more. Kotlin works great with all subsisting Java libraries and frameworks and runs with the same level of performa

In this article, we will show you how to develop a  REST-style web service with Kotlin, Spring Boot, MongoDB. A quick overview of Kotlin, Spring Boot, and MongoDB    Kotlin: It’s a modern programming language targeting the Java platform. Kotlin is concise, safe, pragmatic, and fixated on interoperability with Java code. It can be used virtually everywhere Java is utilized today: for server-side development, Android apps, and much more. Kotlin works great with all subsisting Java libraries and frameworks and runs with the same level of performance as Java.   MongoDB: MongoDB is a document database built on a scale-out architecture that has to propagate with developers of all kinds who are building scalable applications utilizing agile methodologies. MongoDB was built for people who are building internet and business applications who need to evolve expeditiously and scale elegantly. If you are doing that, you should consider MongoDB. Companies and development teams of all sizes use Mongo

Quick Overview - RSA The RSA algorithm (Rivest-Shamir-Adleman) is a cryptographic algorithm that is used for specific security services or purposes, which enables public-key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the HTTP. A public key is shared publicly, while a private key is secret and must not be shared with anyone. The following illustration highlights how asymmetric cryptography works: Example 1 :  RSA Encryption and Decryption The Cipher Type: RSA/ECB/PKCS1Padding import java.security.spec.PKCS8EncodedKeySpec import javax.crypto.Cipher import java.security.spec.X509EncodedKeySpec import java.io.IOException import java.security.* import java.util.* class RSADemo { var privateKey: PrivateKey var publicKey: PublicKey companion object { // convert String publickey to Key object @Throws (GeneralSecurityException:: class , IOException:: class ) fun loadP
