Morse Code
1 minute to read
We are given this sequence of .
and -
:
-.-. - ..-. .-.. . .- .-. -. ... .- -- ..- . .-.. -- --- .-. ... . .. ... -.-. --- --- .-.. -... -.-- - .... . .-- .- -.-- .. .-.. .. -.- . -.-. .... . . ...
As the title of the challenge suggests, it is Morse code. Hence, we must decode the sequence.
We can do it manually: -.-.
is C
, -
is T
, ..-.
is F
… Or we can use an online decoder like morsedecoder.com:
And we get this message:
CTFLEARNSAMUELMORSEISCOOLBYTHEWAYILIKECHEES
So the flag is:
