pyzipper 0.3.6

AES encryption for zipfile.

pyzipper

A replacement for Python’s zipfile that can read and write AES encrypted zip files. Forked from Python 3.7’s zipfile module, it features the same zipfile API from that time (most notably, lacking support for pathlib-compatible wrappers that were introduced in Python 3.8).

Installation

pip install pyzipper

Usage

import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                         'w',
                         compression=pyzipper.ZIP_LZMA,
                         encryption=pyzipper.WZ_AES) as zf:
    zf.setpassword(secret_password)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")

with pyzipper.AESZipFile('new_test.zip') as zf:
    zf.setpassword(secret_password)
    my_secrets = zf.read('test.txt')

AES Strength

The strength of the AES encryption can be configure to be 128, 192 or 256 bits. By default it is 256 bits. Use the setencryption() method to specify the encryption kwargs:

import pyzipper

secret_password = b'lost art of keeping a secret'

with pyzipper.AESZipFile('new_test.zip',
                         'w',
                         compression=pyzipper.ZIP_LZMA) as zf:
    zf.setpassword(secret_password)
    zf.setencryption(pyzipper.WZ_AES, nbits=128)
    zf.writestr('test.txt', "What ever you do, don't tell anyone!")

with pyzipper.AESZipFile('new_test.zip') as zf:
    zf.setpassword(secret_password)
    my_secrets = zf.read('test.txt')
