  2. Use the key to create Rfc2898DeriveBytes?

  • Encryption protocols are language agnostic - it will be the same process/parameters in every language. – James Oct 01 '13 at 09:55
  • I see no relation between your question and the `Rfc2898DeriveBytes` class. Are you sure you know what you want to do and how? See [Why do I need to use the Rfc2898DeriveBytes class (in .NET) instead of directly using the password as a key or IV?](http://stackoverflow.com/questions/2659214/why-do-i-need-to-use-the-rfc2898derivebytes-class-in-net-instead-of-directly), [Encrypt/Decrypt String using DES in C# - CodeProject](http://www.codeproject.com/Articles/19538/Encrypt-Decrypt-String-using-DES-in-C), – CodeCaster Oct 01 '13 at 09:56
  • because given 10-digit security key. – user2813777 Oct 01 '13 at 09:58
