Someone sent this to me...\
*such enigma, such mystery:*\

Settings as below:

* 3 Rotor Model
* Rotor 1: VI, Initial: A, Ring A
* Rotor 2: I, Initial: Q, Ring A
* Rotor 3: III, Initial L, Ring A
* Reflector: UKW B
* Plugboard: `BQ CR DI EJ KW MT OS PX UZ GH`

Given this, we can tell immediately that this is Engima machine cipher. So first things first, I launched up <https://cryptii.com/pipes/enigma-machine>.&#x20;

We get the plaintext that is `messagewrappedinlighthiddendeeperoutofsightlockingitmoretightanywayyourflagishereflagfdfeabcacbebfbadaefbeccaadddbafezzz`

By formatting it a bit better we get

message wrapped in light hidden deeper out of sight locking it more tight anyway your flag is here flag fdfeabcacbebfbadaefbeccaadddbafezzz

So, i thought the flag was `flag{fdfeabcacbebfbadaefbeccaadddbafezzz}`, but this was too long, so i tried removing the final `zzz` characters, giving the the flag as `flag{fdfeabcacbebfbadaefbeccaadddbafe}`.
