WebThe Vigenère cipher is an improvement of the Caesar cipher, by using a sequence of shifts instead of applying the same shift to every letter. A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. Gronsfeld ciphers can be solved as well through the Vigenère tool. WebHowever, a paper and pencil approach is also still doable. 2. Decrypt the ciphertext with the help of the relative letter frequency of the English language. (Substitution Cipher) 1. The ciphertext below was encrypted using a substitution cipher.
