Good morning agent X,
You have been selected for another important mission.
You need to locate a persons flight and the airport were he arrived.
We were able to get the date from his cellphone, but it appears encrypted with some sofisticated technique,
Have a great hunt agent X,

P.S.
We, also, were able to retrieve this:
6tmc`F^ZgDA8*0&i%-!lFWbX7EZf1:+ELt4F)N1CATVs2%178mA8*/sASl@'+Cf>1DKU&8+Cf>-+D5_'DBNP&EdD:J%16TYAKYf'+C\c$FD5<(+CfG7A7]RoASuU$+Co1/Eb0?5D_;

I’m sure that with your capabilities you can solve it.

暂时看不出来是什么,我试了下XOR,无果

然后就尝试附件

6tmc`F^ZgDA8*0&i%-!lFWbX7EZf1:+ELt4F)N1CATVs2%178mA8*/sASl@'+Cf>1DKU&8+Cf>-+D5_'DBNP&EdD:J%16TYAKYf'+C\c$FD5<(+CfG7A7]RoASuU$+Co1/Eb0?5D_;

是base85

在这边,在那边,在那阴森的岩石上,
我看见长着角的魔鬼,手里拿着巨大的鞭子,
在后面残忍地鞭打着他们。

这段文字出自但丁的《神曲》中的《地狱篇》,具体是第十八篇的几行诗句。

后面扒拉了很久

然后终于发现了

是base64
解出

然后搜索dante's inferno cipher(从附件中得知的信息)

你能找到这篇文章

所以我搜索了一下这种编程

https://malbolge.doleczek.pl/

找到这个

一运行

得到一个时间

然后就往前推了,找那个图片的信息

052

勉强恢复了一下

直接google无果

看能不能通过时间反推吧

(尝试了很久,没有结果,暂时搁置)
