How to password protect an object of type ZipFile?

Question

I am trying to send a password protected zip file as a base64 string.

data = BytesIO()
zip = zipfile.ZipFile(data, 'w') 
zip.writestr('test.csv', 'Hello, World')
zip.setpassword(b'1234')
zip.close()
b64zip = base64.b64encode(data.getvalue()).decode('utf-8')

This b64zip variable is then parsed as an email attachment.

However, when I try to unzip the zip it doesn't prompt for a password. Was using this thread for reference:  zipfile: how to set a password for a Zipfile?

How can I create a password protected zip file as a base64 string?

Answer 1

There are some mistakes you made:

1. You've opened a zip file to write and the zip file path is the data itself.
2. You are trying to zip data not files which is wrong. You should encrypt data, not compress it.
3. If you want to compress data write it to TXT file then compress the TXT file.
4. Try using another compression library like: [pyunpack, Pyzipper, pyminizip, …].

I've solved the problem by using pyminizip library:

import pyminizip as pyzip

data = 'stored data'.encode()
with open(".\\data.txt", "wb") as dt : dt.write(data)
pyzip.compress("data.txt", "", "data.zip", "PASSWORD", 8)
