  2. Caesar cipher - Wikipedia

    en.wikipedia.org/wiki/Caesar_cipher

    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. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .

    en.wikipedia.org/wiki/ROT13

    ROT13 is a special case of the Caesar cipher which was developed in ancient Rome, used by Julius Caesar in the 1st century BC. [1] An early entry on the Timeline of cryptography . ROT13 can be referred by "Rotate13", "rotate by 13 places", hyphenated "ROT-13" or sometimes by its autonym "EBG13".

    At the end of every season 1 episode of the cartoon series Gravity Falls, during the credit roll, there is one of three simple substitution ciphers: A -3 Caesar cipher (hinted by "3 letters back" at the end of the opening sequence), an Atbash cipher, or a letter-to-number simple substitution cipher. The season 1 finale encodes a message with ...

    en.wikipedia.org/wiki/Vigenère_cipher

    the second letter t is shifted by 2 (because the second letter C of the key is the 2nd letter of the alphabet, counting from zero) yielding v; the third letter t is shifted by 20 (U) yielding n, with wrap-around; and so on; yielding the message ovnlqbpvt eoegtnh. If the recipient of the message knows the key, they can recover the plaintext by ...

    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]

  7. 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 ...

    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 ...
