  2. Caesar cipher - Wikipedia

    en.wikipedia.org/wiki/Caesar_cipher

    The cipher illustrated here uses a left shift of 3, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques.

    en.wikipedia.org/wiki/Cryptosystem

    A classical example of a cryptosystem is the Caesar cipher. A more contemporary example is the RSA cryptosystem. Another example of a cryptosystem is the Advanced Encryption Standard (AES). AES is a widely used symmetric encryption algorithm that has become the standard for securing data in various applications.

    An early substitution cipher was the Caesar cipher, in which each letter in the plaintext was replaced by a letter three positions further down the alphabet. [23] Suetonius reports that Julius Caesar used it with a shift of three to communicate with his generals. Atbash is an example of an early Hebrew cipher.

    A message encoded with this type of encryption could be decoded with a fixed number on the Caesar cipher. [3] Around 800 AD, Arab mathematician Al-Kindi developed the technique of frequency analysis – which was an attempt to crack ciphers systematically, including the Caesar cipher. [2]

  6. Cipher - Wikipedia

    en.wikipedia.org/wiki/Cipher

    The Caesar Cipher is one of the earliest known cryptographic systems. Julius Caesar used a cipher that shifts the letters in the alphabet in place by three and wrapping the remaining letters to the front to write to Marcus Tullius Cicero in approximately 50 BC. [citation needed] Historical pen and paper ciphers used in the past are sometimes ...

  8. List of cryptographers - Wikipedia

    en.wikipedia.org/wiki/List_of_cryptographers

    Julius Caesar, Roman general/politician, has the Caesar cipher named after him, and a lost work on cryptography by Probus (probably Valerius Probus) is claimed to have covered his use of military cryptography in some detail. It is likely that he did not invent the cipher named after him, as other substitution ciphers were in use well before his ...
