picoCTF 2022 | morse-code Write-up

Challenge description

Morse code is well known. Can you decrypt this? Download the file here. Wrap your answer with picoCTF{}, put underscores in place of pauses, and use all lowercase.

Category: Cryptography


The challenge provided us a .wav file containing morse code in audio form. Obviously, you can try to listen and then note down the code yourself, but I opted instead to use an online tool to analyze and decode it for me (recommended). I used this site and decoded the file in no time at all.

Make sure to edit the output to match the flag’s format before submitting it!
