Hello Everyone,

I hope you are doing well.

Please note that, this CTF competition is over so I have rights to post the writeup publicly according to the policy.

I hope that you have tried all the possible ways to solve the challenge and you are here because you have still not found the solution.

Flag Format: picoCTF{FLAG}

Challenge Details:


  1. Submit your answer in our flag format. For example, if your answer was ‘hello’, you would submit ‘picoCTF{hello}’ as the flag.


In the challenge they have given us hexadecimal value and asked us to convert it to ASCII.

So, I have created a bash oneliner which does the conversion in single command.

echo 0x70 | xxd -r -p

Output: p

Flag: picoCTF{p}

I hope that you have enjoyed the writeup and learned something new today, Please let me know if there are any concerns.

Thank You
