- Classical cipher - Wikipedia
Substitution ciphers In a substitution cipher, letters, or groups of letters, are systematically replaced throughout the message for other letters, groups of letters, or symbols A well-known example of a substitution cipher is the Caesar cipher
- Ciphertext - Wikipedia
Historical pen and paper ciphers used in the past are sometimes known as classical ciphers They include: Substitution cipher: the units of plaintext are replaced with ciphertext (e g , Caesar cipher and one-time pad) Polyalphabetic substitution cipher: a substitution cipher using multiple substitution alphabets (e g , Vigenère cipher and Enigma machine) Polygraphic substitution cipher: the
- Cipher - Wikipedia
When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext The ciphertext message contains all the information of the plaintext message, but is not in a format readable by a human or computer without the proper mechanism to decrypt it
- Beale ciphers - Wikipedia
The second message even cross-references first one, despite Beale supposedly wanted to send Morris a key to all of the three ciphers altogether [10] Also, the original sale price of the pamphlet, 50 cents, was a high price for the time ($17 50 in 2024), and the author wrote that he expected "a wide circulation"
- History of cryptography - Wikipedia
Essentially all ciphers remained vulnerable to the cryptanalytic technique of frequency analysis until the development of the polyalphabetic cipher, and many remained so thereafter The polyalphabetic cipher was most clearly explained by Leon Battista Alberti around AD 1467, for which he was called the "father of Western cryptology" [1]

Articles relating to ciphers, algorithms for performing encryption or decryption To encipher or encode is to convert information into cipher or code In common parlance, "cipher" is synonymous with " code ", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography
