RS256 Support

[Sparika]

Hi,

I'm working on a fork of your project where I need asymmetrical signature for ID Token. I implemented it in my version but I'm not really satisfied with how I did it (ugly). Would you consider adding RS256 algorithm support? Or should we discuss how I could contribute/help?
