WebHistory of Cryptography. Cryptography began with ciphers, the first of which was the Caesar Cipher. Ciphers were a lot easier to unravel compared to modern cryptographic algorithms, but they both used keys and plaintext. Though simple, ciphers from the past were the earliest forms of encryption. Today’s algorithms and cryptosystems are much ... 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 …
