Decryption: Decryption is performed by going to the row in the table corresponding to the key, finding the position of the ciphertext letter in this row, and then using the column’s label as the plaintext. For example, in row A (from AYUSH), the ciphertext G appears in column G, which is the first plaintext letter. harry potter lightning fanfiction

WebFeb 20, 2024 · Lookup Tables. While Vigenère may be comparable to Ceasar ciphers in terms of shifting characters 'modulo the alphabet', the lookup table can vary such as in the case of a DIANA lookup table which given the same ciphertext would produce a different message given the same key (compared to a Vigenère lookup table).
