# Zipped Up
This challenge was a fairly standard recursive archive extraction challenge
with a slight twist in that the file containing the flag isn't actually the
one nested the deepest.
The code rather speaks for itself, so without further ado, here it is.
```py
import tarfile, io
from zipfile import ZipFile
import sys
sys.setrecursionlimit(100000)
def handle(name, data):
if name.endswith('.txt'):
if b'n0t_th3_fl4g' not in data:
print(data)
quit()
elif '.tar' in name:
extract_tar(data, name.split('.')[-1])
elif '.kz3' in name:
extract_zip(data)
def extract_zip(data):
dat = io.BytesIO()
dat.write(data)
dat.seek(0)
zip_file = ZipFile(dat)
for name in zip_file.namelist():
data = zip_file.read(name)
handle(name, data)
def extract_tar(data, mode):
dat = io.BytesIO()
dat.write(data)
dat.seek(0)
tar_file = tarfile.open(fileobj=dat, mode='r:' + mode)
for i in tar_file:
data = tar_file.extractfile(i).read()
handle(i.name, data)
if __name__ == '__main__':
extract_tar(open('1.tar.bz2', 'rb').read(), 'bz2')
```
