Python实现字符串与指定密钥循环异或加解密 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...
reverse_write稍后可以调用original_write,因为它在其闭包中可用。 ④ 将sys.stdout.write替换为reverse_write。 ⑤ 产生将绑定到with语句中as子句的目标变量的值。生成器在此处暂停,而with的主体执行。 ⑥ 当控制退出with块时,执行继续在yield之后;这里恢复原始的sys.stdout.write。
