Write C# Function To Decrypt Hole Cards For A Poker Bot

I am creating a poker bot to play no-limit Texas holdem on the Poker Mavens poker platform by briggs softworks. I am reverse engineering the client/server protocol to create the bot and coding the bot in C#. The Poker Mavens server is written in Delphi XE5 and the client is written in HTML5/Javascript. The client and server communicate by sending JSON payloads back and forth over a websocket connection. As of right now, my bot can establish a websocket connection to the server, login and select an open seat at the specified table and sit. The next phase is being able to read the cards that are dealt to the bot which are encrypted with sha256 hash that uses a seed. I have the client Javascript file that contains the functions needed to decrypt the hole cards and need an experienced Java/C# programmer to step through the Javascript file and write the equivalent C# methods/function to accomplish the same task. I will provide everything needed to get started and test and will be available to answer any questions or help. I need someone experienced in Java and C# .Net that will stay on task and get the job done and provide status updates or ask questions if there is an issue. If this sounds like you, please bid on the project for immediate consideration. There will also be a bonus for the freelancer if this project can be completed in a timely manner. Look forward to hearing from you.
