Mar 18,  · Vigenere Cipher - Decryption is tricky. The vigenere cipher works like this: You have two text strings; a message (plain text), and a keyword. To encrypt each letter, you use the vigenere square. The first letter of the message is 'E' - therefore we go to the 'E' column (cell F1) The first letter of the keyword is 'M' - so we go to the 'M' row. Mar 04,  · Hi, I am struggling with some Cryptography homework with a Vigenere Cipher in Excel. - I have to enter a formula to calculate the ciphertext values in cells ABAH10 - I have to enter a formula that uses the translation table in cells AB55 to calculate a translation factor for each letter of the key in cells ABAH - Lastly, use the translation tables in cells ACAD55 to convert the. Encryption with Vigenere uses a key made of letters (and an alphabet). Vigenere Ciphering by adding letters In order to cipher a text, take the first letter of the message and the first letter of the key, add their value (letters have a value depending on their rank in the alphabet, starting with 0).
