id did it with python. what would be the way to "decript" this with bash?

it's binary

not easy , at all ... its an idea for med and hard .

hint: in binary: space is a zero, dot is a one

elo... first cyberchef - find/replace (space to 0, point to 1) next conwert bin to txt and go to flag

it is quite hard.

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.

For those that are stuck, what is another way to interpret an empty space and a filled space?

Great hint ;)

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 :)
