WebMar 21, 2024 · XOR Cipher. XOR Encryption is an encryption method used to encrypt data and is hard to crack by brute-force method, i.e generating random encryption keys to match with the correct one. Below is a simple implementation in C++. The concept of implementation is to first define XOR – encryption key and then to perform XOR operation … WebCryptography uses mathematical techniques to transform data and prevent it from being read or tampered with by unauthorized parties. That enables exchanging secure messages even in the presence of adversaries. Cryptography is a continually evolving field that drives research and innovation.
