TryHackMe - Intro to Python
Challenge Location: TryHackMe
This lesson is fairly straightforward, but necessary to complete for one (or more) of the learning paths. I’m already confident with Python, so here’s my solution to the challenge problem.
You’ll find a file attached to this task called encoded_flag.txt. Within this file, you will find some encoded information! This is your challenge as follows;
Using the base64 library within python. Can you decode this and retrieve the flag? Note this has been encoded a total of 15 times. Be sure to read from the file provided and the documentation for the base64 library.
import base64 file = open("encodedflag.txt","r") encoded = file.readline() for i in range(0,5): encoded = base64.b16decode(encoded) for i in range(0,5): encoded = base64.b32decode(encoded) for i in range(0,5): encoded = base64.b64decode(encoded) f = open("decodedflag.txt","w") f.write(encoded.decode()) f.close()
