I've just graduated the Super Agent School. This is my first day as a spy. The Master-Mind sent me the secret message, but I don't remember how to read this. Help!

hint: in binary: space is a zero, dot is a one
Don't know what encryption this is. Any help?
you can try xxd
Still can't figure it out.
you see dots and spaces. That's the biggest hint
bro if I tell you the next step, it will be the solution and anyone who view the comments will get the flag ..................focus on what these dots and spaces can represent. Spend some time on it . Try different things. I am sure you will get the flag.
Thanks , this was on 'easy' sector so I understimated it. Had to write a small program for it but got it.
:D
Was really hard. I don't think it should be in the easy section! For those still searching, don't look for pattern, understand why there is dot and blank.
Another nice challenge to train you not to overthink.
I don't know how to program yet (only recently started, so still a noobie) but I found a way to do this by simply using Cyberchef. I first tried opening using notepad and by using select-all, I could see there was something in there but just couldn't view it. By opening the file in Cyberchef, you can see it's a series of dots and spaces. I was stumped at first but from the comments, I realised it was binary, so I copied them and made them the input in Cyberchef. I tried manually changing them to 1's and 0's but after messing it up twice (and wasting two hours), I googled and realised you can use Cyberchef to convert them using Find/Replace. Then I used from Binary and the message was revealed :)
