有没有办法让这个代码“正常”呢

Question

我正在解码/解密这段代码，python看起来像This

Answer 1

这并不是一个完整的答案，但在取消转义并打印出来时，大多数文件看起来都是正确的。例如，只需将粘贴从decoded.txt文件复制到python REPL中并打印出来即可：

>>> print(
... """\r\n@Exeter.command(aliases=["stopcopycatuser", "stopcopyuser", "stopc
... opy"])\r\nasync def stopcopycat(ctx):\r\n    await ctx.message.delete()\r
... \n    if Exeter.user is None:\r\n        await ctx.send("You weren\'t cop
... ying anyone to begin with")\r\n        return\r\n    await ctx.send("Stop
... ped copying " + str(Exeter.copycat))\r\n    Exeter.copycat = None\r\n"""
... )

@Exeter.command(aliases=["stopcopycatuser", "stopcopyuser", "stopcopy"])
async def stopcopycat(ctx):
    await ctx.message.delete()
    if Exeter.user is None:
        await ctx.send("You weren't copying anyone to begin with")
        return
    await ctx.send("Stopped copying " + str(Exeter.copycat))
    Exeter.copycat = None

使用decoded.txt以编程方式完成此任务的一种方法是：

with read("decoded.txt") as f:
    data = f.read()

unescaped = data.encode("utf8").decode("unicode_escape")
print(unescaped)

Answer 2

代码只是使用b64编码。要对其进行解码，您只需打印传递给eval的结果

data = ((base64.b64decode(eval('\x74\x72\x75\x73\x74')),'<string>','exec'))
print(data[0].decode("utf-8"))

如果要避免评估，可以使用

joy = 'rot13'

trust = magic + codecs.decode(love, joy) + god + codecs.decode(destiny, joy)

code = (base64.b64decode(trust),'<string>','exec')
print(code[0].decode("utf-8"))
