A litle off topic but the zipfile doc says: "Decryption is extremely slow as it
is implemented in native python rather than C".

Why is this limitation there? I mean, is there any specific reason for not implementing
it in C?

Actually, the issue posting doesn't say either way - it doesn't provide
any real use cases at all.

For local protection of confidential information there are already much
better solutions out there (e.g. whole disk encryption, OS file
permissions, OS folder encryption), so a poor-man's DRM was the only
remaining remotely plausible use case I could see (and that's a bad idea
for all the reasons that DRM is almost always a bad idea).

Now, that could just be a failure of imagination on my part, but genuine
use case suggestions for the feature have been non existent so far.

Cheers,
Nick.
