日常偷懒挂代码，之后有空再讲解

预览

分不同的加密模式（分参数不同导致密文效果不同，以及解码的原理不同两种），单数字加密只能加密一个数字，这个数字可以很大，只要小于模数（大素数1和大素数2的乘积）就行，全字符加密可以任意输入任何内容，均可进行加密，自定义模数需要自行设定参数，乱码格式和框框模式，密文显示不同，如加密“python天下第一”“博主好帅”等等，结果如下

乱码格式：鋇𤆋𧏀�𙠇𡬰𫦥𝱶𕫂

框框模式：𡝫񈮗󑹜񝅙򄤁񾃈񈝗𰗒񾺘󈘦

再比如加密一段代码

def Mutual_prime(num1,num2): #求解最大公因数是否为1
    flag = False
    while True:
        if num1>num2:
            if(num1%num2==0):
                if(num2==1):
                    flag=True
                    break
                else:
                    break
            else:
                num1,num2=num2,num1%num2
        else:
            num1,num2=num2,num1
    # if Greatest_common_divisor(num1,num2)==1:
    #     flag=True
    return flag
