The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). So key 2 encrypts "HI" to "JK", but key 20 encrypts "HI" to "BC". This simple "monoalphabetic substitution cipher" provides almost no security, because an attacker who has the ...
第34 行调用我们在affinicipher.py中使用的getKeyParts()函数,将一个整数密钥分成两个整数。在这个例子中,我们使用函数来获取我们正在测试的密钥的一部分。回想一下,这个函数调用的返回值是两个整数的元组:一个用于密钥 A,一个用于密钥 B。第 34 行通过将[0]放在hackAffine()函数调用之后,将元组的第一个整数...

Caesar Cipher is a type ofsubstitution cipher, in which each letter in the plain text is replaced by another letter at some fixed positions from the current letter in the alphabet. For example, if we shift each letter by three positions to the right, each of the letters in our plain text...

In this example, \xc3\xb1 is the escape sequence for the letter ñ in the Spanish word "España". Note that if you try to use the ñ directly, you get a SyntaxError. The Built-in bytes() Function The built-in bytes() function provides another way to create bytes objects. With...
