OoxmlCrypt

A Ruby library for encrypting/decrypting password-protected Microsoft Office XML (OOXML) files (e.g. .docx, .xlsx, .pptx). This is a native extension that builds on top of the msoffice library. This only supports documents encrypted (i.e. password-protected) by Office 2010 or later.

Add this line to your application's Gemfile:

gem 'ooxml_crypt'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install ooxml_crypt

To encrypt, you can either pass in a file or binary data:

require "ooxml_crypt"

# pass in binary data, get binary data
encrypted_data = OoxmlCrypt.encrypt(bindata, password)

# or use file names
OoxmlCrypt.encrypt_file(filename, password, encrypted_filename)

The same approach holds true for decryption:

require "ooxml_crypt"

# pass in binary data, get binary data
decrypted_data = OoxmlCrypt.decrypt(bindata, password)

# or use file names
OoxmlCrypt.decrypt_file(filename, password, decrypted_filename)

An exception OoxmlCrypt::Error will be raised in case of errors.

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
