WebFeb 15, 2024 · As an essential aspect of modern data security, using cryptography allows the secure storage and transmission of data between willing parties. Here are a few terminologies which will help you understand what cryptography is, with better clarity. There are two primary aspects of cryptography, they are: 1. Encryption. The primary reason XOR is so useful in cryptography is because it is "perfectly balanced"; for a given plaintext input 0 or 1, the ciphertext result is equally likely to be either 0 or 1 for a truly random key bit. The table below shows all four possible pairs of plaintext and key bits. It is clear that if nothing is known about the key or plaintext, nothing can be determined from the ciphertext alone. raya shankhwalker architects
