Is it possible to have ZIP file that has a data descriptor, and so the compressed size of each file is after its data, and have it password-protected via ZIP’s “weak” encryption mechanism?
Context: am working on a streaming unZIP function for Python, specifically adding decryption support. Not being able to depend on the compressed size known before the data makes it… awkward.

Made with Info-ZIP’s zip thusly:
echo -n 'hello, hello! ' | zip -e | cat > foo.zip
