SignedApi

SignedApi gem offers easy way to make your web APIs secure by using secret key based signature authentication. This uses the similar way as AWS's signed URLs.

Installation

Add this line to your application's Gemfile:

gem 'signed_api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install signed_api

Usage

Client side

You can easily sign your params by sign_params method

  signed_params = SignedApi::sign_params('GET', '/api/search', {a: 'param_a', b: 'param_b', c: 'param_c'}, 'SOME_KEY', 'SOME_SECRET_STRING', 60)

or you can directly make a signed URL like this.

  signed_url = SignedApi::get_signed_url('https://example.com', 'GET', '/api/search', {a: 'param_a', b: 'param_b', c: 'param_c'}, 'SOME_KEY', 'SOME_SECRET_STRING', 60)

Server side

You can verify the request easily.

  begin
    SignedApi::verify_signature!(method, path, params) {|key| secrets[key]}
  rescue
    # log error and return error to the client
  end
