This discussion of classical ciphers illustrates some of the fundamental principles that remain relevant in modern cryptography. While these classical methods are no longer secure, they introduce core concepts like the importance of key management and that key secrecy is more important than al...
Classical ciphers are cryptographic algorithms that have been used in the past (pre WWII). Some of them have only ever been used by amateurs (e.g. Bifid), while some of them have been used by armies to secure their top level communications (e.g. ADFGVX). None of these algorithms are ...

where the set of related monoalphabetic substitution rules consists of the 26 Caesar ciphers, with shifts of 0 through 25. Each cipher is denoted by a key letter, which is the ciphertext letter that substitutes for the plaintext letter ‘a’, and which are each used in turn, as shown nex...
