ROT13 Decoder Explained: How This Classic Cipher Works
ROT13 is one of the simplest and most famous ciphers in the world of cryptography. Even though it is very old and not secure by modern standards, it is still widely used today. Many beginners learn about encryption and decryption for the first time through ROT13 because it is easy to understand and fun to use. In this guide, you will learn what the ROT13 cipher is, how it works, and why people still use it. This blog is written in very simple English so anyone can understand it, even if you have no technical background. By the end of this article, you will clearly understand how a ROT13 decoder works and when it should be used. What Is a ROT13 Cipher? ROT13 is a type of substitution cipher. A substitution cipher is a method where each letter in a message is replaced with another letter. In the case of ROT13, every letter is replaced by the letter that comes 13 positions after it in the English alphabet. The name ROT13 comes from the word “rotate” and the number 13. It means rota...
