A gem to add secured file uploading to CarrierWave. Uses Crypt19 and OpenSSL to encrypt and decrypt files, and offers multiple methods of encryption.

I needed this functionality for a project, and simply couldn't find a viable solution. So I rolled out my own. Then I got tired of dirtying up my /lib/ folder, so I made a gem out of it. This is my first attempt at writing a gem, and for my project, it works pretty well.

For personal testing, I was uploading to RackSpace Cloud Files. I haven't tested using local file uploads or other cloud services, but it should work fine just the same.

Ruby 1.9.3 w/ Rails 3.1.3. Realistically, it should work on Ruby 1.9.x and Rails 3.x, but may work on other configurations. It hasn't been tested. I'm currently using this with CarrierWave 0.6.2, Rails 3.2.8, and Ruby 1.9.3.

Please refer to the Wiki For Installation and Usage.

• Added AES file encryption using OpenSSL

• Changed syntax for Downloader so, you know, it actually works. Would expect a "user_file" field before, now you specify the file field.
• Added choice for encryption algorithm - Blowfish (default), Rijndael, GOST.

• Integrate with 'process' method in uploader to make 4 lines of code into 1
• Refactoring and testing

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
• Fork the project
• Start a feature/bugfix branch
• Commit and push until you are happy with your contribution
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
