# Every day i'm shuffling (Crypto) \[481\]
## __Description__

## __Solution__
```def main():    file_name = 'message_from_above'    data = open(file_name + '.txt', 'r').read()    seed(randint(1, len(file_name)))    file_name = list(file_name)    shuffle(file_name)```
We know that \'message_from_above\' became \'fsegovs_meaoerbma\', so I try seeding 1~18 and shuffling filename to see whether it matches.
The seed is 3, now we shuffle the list and reverse it.
```pp = list(range(len(data)))shuffle(pp)p = [0]*len(pp)for i in range(len(pp)):    p[pp[i]] = i```
Then use this mapping to reverse the whole process.
The flag can be found in [message_from_above]('message_from_above.txt)
