In today’s world, securing data is a top priority, and encryption algorithms play a crucial role in this process. Encryption is essentially the method of converting data into a form that unauthorized parties cannot understand. If you’re just starting out, this guide will introduce you to some of the most popular encryption algorithms, where and when to use them, and provide Kotlin code examples for each. What are Encryption Algorithms? Encryption algorithms are mathematical formulas used to transform readable data (plaintext) into an unreadable format (ciphertext) and vice versa (decryption). The goal is to ensure that sensitive information remains confidential and secure during transmission or storage. Where, When, and Why to Use Encryption Algorithms Where to Use: Data Transmission : When data is transmitted over a network (e.g., sending emails or communicating via messaging apps), encryption protects the data from being intercepted and read by unauthorized users. Data Storage : Encr...
