evy-driven随机过程

"evy-driven"是一个术语，通常用于描述随机过程中的一种特定形式。具体来说，如果一个随机过程是evy-driven的，那么它的变化率取决于一个叫做evy过程的外在因素，而不是内在的随机性。

evy过程是一种具有稳定分布的随机过程，它通常用于模拟金融市场中的波动性。evy-driven随机过程可以用来描述股票价格、汇率、商品价格等的变化，以及其他一些随机现象。

该代码通过异或解密和base64解码得到一个Python代码对象，然后使用marshal模块的loads函数将其转换为可执行的代码对象。最后通过exec函数执行该代码对象。

根据给定的密钥，我们可以使用Sympy库计算出一个积分值，并将其与给定的检查值进行比较，如果相等，则可以进行解密操作。以下是解密代码：

xor_key = int(input('Plz input key (0<key<100):'))

# 计算积分值
integral_value = (xor_key ** 2) / 2 + xor_key + 2/3

check_value = 13024

if integral_value * 3 == check_value:
    # 异或解密
    xor_decoded_data = bytes([byte ^ xor_key for byte in encoded_data])
    # base64解码
    decoded_data = base64.b64decode(xor_decoded_data)
    # 反序列化为可执行代码对象
    code_obj = marshal.loads(decoded_data)
    # 执行代码
    exec(code_obj)
else:
    print('Wrong!!')

输入密钥后，程序将计算出积分值，并与给定的检查值进行比较，如果相等，则进行解密操作，并最终执行解密后的代码对象。

这段代码的作用是输入一个密钥，对一个编码后的数据进行异或解密，并使用 base64 解码和 marshal 反序列化得到一个 Python 代码对象，最后执行这个代码对象。其中，解密密钥必须在 0 到 100 之间，且解密后的数据需要满足某个积分值为 13024 的条件才能被正确解密。如果积分值不符合条件，程序会输出 "Wrong!!"。
