Base64

In Python, after importing the base64 module with import base64, you can use the base64.b64encode() function. Remember to decode the hex first as the challenge description states.

Solution

import base64
hex_string = '72bca9b68fc16ac7beeb8f849dca1d8a783e8acf9679bf9269f7bf'
given_bytes = bytes.fromhex(hex_string)
flag = base64.b64encode(given_bytes).decode()
print(f"{flag}")
