Also, encryption is all about maths, so there are hundreds of ways to do just about anything, different parameters, different algorithms with different tradeoffs about speed, performance, resistance to attacks, data bandwidth, etc. etc. So I don't think a library with the kind of interface you describe would be very useful. But I do think it would be great to have a library that allows us to configure encryption based on requirements instead of technicalities.
