Vignere密码使用一组以上的替换,因此它也被称为polyalphabetic cipher。 Vignere Cipher将使用字母键而不是数字键表示:字母A将用于键0,字母B将用于键1,依此类推。 加密过程之前和之后的字母数量如下所示 - 基于Vignere密钥长度的可能密钥数量的可能组合如下给出,其给出了Vignere密码算法的安全性的结果 - Vignere Tableau 用于Vignere密码的画面如下所示 -
考虑文本This is basic implementation of Vignere Cipher进行编码,使用的密钥是PIZZA. Code 您可以使用以下代码在Python中实现Vignere密码 - import pyperclip LETTERS = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' def main(): myMessage = "This is basic implementation of Vignere Cipher" myKey = 'PIZZA' myMode = 'encrypt...

The first step of Kasiski examination is to find every repeated set of at least three letters in the ciphertext. These repeated sequences could be the same letters of plaintext encrypted using the same subkeys of the Vigenère key. For example, if you encrypted the plaintext THE CAT IS ...
