Xor–encrypt–xor

Xor-encrypt-xor (often abbreviated as XEX) is a simple symmetric encryption technique based on the bitwise XOR (exclusive OR) operation. The fundamental idea behind this method is to use the XOR operation to encrypt and decrypt data. Here's a basic overview of how it works: 1. **XOR Operation**: The XOR operation is a binary operation that takes two bits and returns 1 if the bits are different and 0 if they are the same.
