Python code to create a password encrypted zip file? [duplicate]

Answer 1

To create encrypted zip archive (named 'myarchive.zip') using open-source 7-Zip utility:

rc = subprocess.call(['7z', 'a', '-pP4$$W0rd', '-y', 'myarchive.zip'] + 
                     ['first_file.txt', 'second.file'])

To install 7-Zip, type:

$ sudo apt-get install p7zip-full

To unzip by hand (to demonstrate compatibility with zip utitity), type:

$ unzip myarchive.zip

And enter P4$$W0rd at the prompt.

Or the same in Python 2.6+:

>>> zipfile.ZipFile('myarchive.zip').extractall(pwd='P4$$W0rd')

Answer 2

If Python is not a must and you can use system utilities, tools like zip or rar provides password encrypted compression. zip with -e option, and rar with -p.

Answer 3

Extraction is pretty easy, you just use zipfile.ZipFile.setpassword() which was introduced in python 2.6, however the standard python library lacks support for creating encrypted zip files.

There are commercially available libraries for Python which supports creation of encrypted and password protected zip files. If you want to use something freely available, you need to use the standard zip command line utility.

zip -e -Ppassword filename.zip fileA fileB ...

Answer 4

You can use Pygpgme to create a password-protected gpg file, which is compressed.

You'll need to use the equivalent of gpg -c myFile or gpg --symmetric myFile and gpg myFile.gpg

I don't know what the equivalents are in that Python module, but I know they've existed since version 0.2. There was a bug report before then mentioning the lack of it, but someone released a patch and they fixed it in version 0.2.

This uses symmetric encryption so you don't have to worry about keys.

You might find my post asking how to use it on UbuntuForums. Feel free to answer it if you know.

Answer 5

Actually setpassword("yourpassword") is only valid for extracting, not for creating a zip file.

The solution(not to my liking):
