pfpro4r is a set of bindings for [2]Verisign''s Payflow Pro SDK. If you''re distributing an app in Ruby/Rails and you use Verisign''s Payflow Pro, you basically have three options (paraphrased from the [3]RoR Wiki): 1. Call the Java/Perl/PHP API from Ruby. (Ewww...) 2. Call Verisign''s command line scripts. (DO NOT DO THIS. This is highly vulnerable to [4]shell injection attacks.) 3. Code a ruby extension which makes use of the Payflow shared library API and make calls directly from Ruby. pfpro4r is an implementation of the last option. http://www.livemetric.com/opensource/pfpro4r References 1. http://www.livemetric.com/ 2. http://www.verisign.com/products-services/payment-processing/online-payment/ payflow-pro/index.html 3. http://wiki.rubyonrails.org/rails/pages/Verisign 4. http://en.wikipedia.org/wiki/Code_injection#Shell_Injection -------------- next part -------------- An HTML attachment was scrubbed...
