This forms 26 rows of shifted alphabets, ending with an alphabet starting with Z (as shown in image). Separate from these 26 alphabets are a header row at the top and a header column on the left, each containing the letters of the alphabet in A-Z order. The tabula recta can be used in several equivalent ways to encrypt and decrypt text.
The Vigenère square or Vigenère table, also known as the tabula recta, can be used for encryption and decryption. In a Caesar cipher, each letter of the alphabet is shifted along some number of places. For example, in a Caesar cipher of shift 3, a would become D, b would become E, y would become B and so on. The Vigenère cipher has several ...
A tabula recta for use with an autokey cipher An autokey cipher (also known as the autoclave cipher ) is a cipher that incorporates the message (the plaintext ) into the key . The key is generated from the message in some automated fashion, sometimes by selecting certain letters from the text or, more commonly, by adding a short primer key to ...
Each alphabet was shifted one letter to the left from the one above it, and started again with A after reaching Z (see table). Tabula recta. Trithemius's idea was to encipher the first letter of the message using the first shifted alphabet, so A became B, B became C, etc.
"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 key text used is a portion of The C Programming Language (1978 edition), and the tabula recta is the tableau. The plaintext here is "Flee at once". Page 63, line 1 is selected as the running key: errors can occur in several places. A label has... The running key is then written under the plaintext:

The letter compared with E/e, in fonts Arial, Times New Roman, Cambria, and Gentium Plus. Ǝ ǝ (turned E or reversed E) is an additional letter of the Latin alphabet used in African languages using the Pan-Nigerian alphabet. The minuscule is based on a rotated e and the capital form majuscule Ǝ, based on a reversed (mirrored) majuscule E.
