Can rubyzip do password protected files?

[José Luis]

Hi.

I've been looking at the rubyzip docs and haven't found anything
concerning ziping/unziping password protected files.

Does rubyzip or any other lib have that capability?

Thanks in advance.

I ran into this myself recently. Rubyzip is a wrapper around the zlib
compression library.

Zlib itself doesn't support password protected zips. There is another
library made by the same folks that created zlib called Info-zip. It
does support password protection but you'll have to write your own to
wrapper to make it a Ruby extension.

N.B. There's a comment in the source for info-zip that implies that
the password protection handling is hard to work with. I found that to
be the case. In the end, I purchased a third party compression library
(from ChilKat).

I had a feeling that would be the case.
Thanks for the tip.
