异或运算在很多密码学算法中都有不同程度的应用,其运算特定在于一个数和另一个数连续异或两次仍得到原来的数。在实际使用中,因为要加密的信息和所使用的密钥在大多数情况下是不等长的,所以经常需要循环使用密钥。 def crypt1(source, key): '''source是要加密或解密的字符串,key是密钥字符串''' ...

与换位密码测试程序一样,换位文件密码程序导入transpositonecrypt.py和transpositonecrypt.py文件,以便调用encryptMessage()和decryptMessage()函数。因此,您不必在新程序中重新键入这些函数的代码。 选择文件 -> 新文件,打开新文件编辑器窗口。在文件编辑器中输入以下代码,保存为transpositionfilecipher.py。然后从www.no...

Going to the decryption function now, it is the same process, except we will use the decrypt() function instead of encrypt() on the Fernet object:def decrypt(filename, key): """ Given a filename (str) and key (bytes), it decrypts the file and write it """ f = Fernet(key) ...
