hello world welcome back to another imaginary CTF 2024 writeup video in this video weamp;#39;ll be walking through the crypto challenge base 64 letamp;#39;s get into it yet another B 64 decoding challenge okay so I have the files that give you downloaded over here letamp;#39;s go ahead and open this in code okay you have a main.py source code and an out.txt file with the secret key scanning through this main.py script we see that we have a Q being assigned the value 64 and then itamp;#39;s opening the flag file and then converting the flag to a long integer then itamp;#39;s initializing the secret key list and then itamp;#39;s looping through our flag integer and then itamp;#39;s appending to the secret key the flag integer mod Q so the remainder of the flag integer divided by q and then it floor divides the flag integer by q and then it assigns the flag integer to the quotient of that operation so itamp;#39;s clear that we need to reverse this so what Iamp;#39;m going
