Recently I have been in the project to develop Wechat Mini programs, and when it comes to the part of decrypting data, I find out there does not exist a Ruby Gem for this although the Wechat official provides code sample but it is only for Python/PHP/C++. So I decided to resemble the Python source code and write a Ruby Gem based on it.
The Gem is called
wx_biz_data_crypt, and its source code is at (https://github.com/yanyingwang/wx_biz_data_crypt).
This is a very simple Ruby Gem, it only provides the basis of the Wechat Descrypt Data Algorithm, and the home page of the source code is documenting the installation and uage of it.
