Cypher cryptography
WebThe Caesar cipher (or Caesar code) is a monoalphabetic substitution cipher, where each letter is replaced by another letter located a little further in the alphabet (therefore shifted but always the same for given cipher message). The shift distance is chosen by a number called the offset, which can be right (A to B) or left (B to A). WebNov 12, 2024 · Cryptography is an art born with politics and war from the necessity of communicating at a distance preventing eavesdroppers from understanding the message. The earliest examples are the Greek, Roman and Arab cyphers, based on various kind of pre-defined letter substitutions. The first true leap forward in cryptography in the first …

An encryption algorithm takes in a plaintext message, runs the algorithm on the plaintext, and produces a ciphertext. The ciphertext can be reversed through the process of decryption, to produce the original plaintext.
