Zip and AES encrypt in Rails

1
votes

What's the easiest way to zip and encrypt a file with AES (128 or 256) in a Rails app, so that the zip archive can be opened with WinZip?

Requirements:

  1. Zip archive can be opened by WinZip (so no 7-zip)
  2. Zip archive is encrypted with AES-128 or AES-256 (which WinZip supports)

Gems:

  1. Rubyzip: doesn't support encryption
  2. Zipruby: supports only the traditional/legacy non-AES encryption which is significantly less secure.

Any advice on what I can do here?

Thanks!

Are commercial products out of the question? Chilkat Ruby Zip appears to support WinZip AES. The example code looks pretty temptingly easy.

There also appears to be a Java library available. If you're running in JRuby... Or if you feel like porting!
