The second table, appropriately called the inverse, does the opposite: it can be used to deduce a possible triplet code if the amino acid is known. As multiple codons can code for the same amino acid, the International Union of Pure and Applied Chemistry 's (IUPAC) nucleic acid notation is given in some instances.
The Caesar cipher is named for Julius Caesar, who used an alphabet where decrypting would shift three letters to the left. The Caesar cipher is named after Julius Caesar , who, according to Suetonius , used it with a shift of three (A becoming D when encrypting, and D becoming A when decrypting) to protect messages of military significance.

Mitchell T. Lavin, whose "chump" was published in June, wrote, "I think it is in the only word in the English language which has this peculiarity," while Clarence Williams wrote, about his "Bet" ambigram, "Possibly B is the only letter of the alphabet that will produce such an interesting anomaly." [34] [35]
In a K2 Aristocrat Cipher, the ciphertext alphabet is constructed by placing the keyword at the beginning of the alphabet, followed by the remaining letters in their standard order, omitting those already used in the keyword. This method ensures that each letter in the plaintext is substituted by a different letter in the ciphertext.
To encode message: A becomes N, B becomes O, and so on up to M, which becomes Z, then the sequence continues at the beginning of the alphabet: N becomes A, O becomes B, and so on to Z, which becomes M. To decode a message, You apply the same substitution rules, but this time on the ROT13 encrypted text.
The Atbash cipher is a particular type of monoalphabetic cipher formed by taking the alphabet (or abjad, syllabary, etc.) and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example, the Hebrew alphabet would work like this:
"The Alphabet Cipher" was a brief study published by Lewis Carroll in 1868, describing how to use the alphabet to send encrypted codes. [1] It was one of four ciphers he invented between 1858 and 1868, and one of two polyalphabetic ciphers he devised during that period and used to write letters to his friends.
The Baconian alphabet is then used to recover the original message. Any method of writing the message that allows two distinct representations for each character can be used for the Bacon Cipher. Bacon himself prepared a Biliteral Alphabet [ 5 ] for handwritten capital and small letters with each having two alternative forms, one to be used as ...
