32 + 32 = 64

Description

64 is too much, but 32 isn't. 32+32=64?

32_1.txt, 32_2.txt

Solution

We are given 2 files which seems to contain Base64 encoded data, after decoding we still get Base64. File needs to be Base64 decoded 32 times (hence the name).

from base64 import b64decode as bd

with open('./32_1.txt') as f: data1 = f.read().strip()
with open('./32_2.txt') as f: data2 = f.read().strip()

for i in range(32):
    data1 = bd(data1).decode()
    data2 = bd(data2).decode()

print(f"{data1}{data2}")
