So I am interested in computer security, cryptography and security protocols. Thing is, everything I read is about theoretical usage of protocols, but how do those things work in real world?
Is there a book or paper that I can read and understand how everything works practically. Like how everything is implemented programically, not just on paper? I am not talking about implementation of cipher itself programically, but how everything works together? Let's say I login to internet banking and lot's of stuff happen automatically regarding encryption, sessions, etc., but how can I see real world example of what is happening there?
