3 Ways to Encode and Decode Using the Vigènere Cipher - wikiHow

The Vigenere Cipher:This problem explores the use of a one-time pad version of the Vigenere cipher. In this scheme, the key is a stream of random numbers between 0 and 26. For example, if the key is 3 19 5, then the first letter of the plaintext is encrypted with a shift of 3 letters, the second with a shift of 19 letters, the third with a shift of 5 letters, and so on. Encrypt the plaintext "sendmoremoney" with the keystream 9 0 1 7 23 15 21 14 11 11 2 8 9.Using the ciphertext obtained in part
