Steps

This was a new challenge. I started by googling enigma cipher and discovered Enigma-Machine. I pasted in the cipher text and mirrored the settings within the challenge and got this response:

I can see the text has odd spacing, so I cleaned up the formatting and have this result:

message wrapped in light hidden deeper out of sight locking it more tight any way your flag is here flag fdfea bcacbebfbadaefbeccaadddbafezzz

After some quick trial and error I found the flag as: flag{fdfeabcacbebfbadaefbeccaadddbafe}

Flag: flag{fdfeabcacbebfbadaefbeccaadddbafe}
