Although I might pretend very well that I known a thing about networks or security and it might help me pass an interview, or fix a bug, I don't really feel I'm fooling anyone. I'm looking for a laymen terms explanation of nowadays network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies" like me (e.g experienced Java developers that can speak the jargon but have no real clue what it means)

Topics I have a weak notion about and want to understand better as a Java developer

PGP
Public / Private keys
RSA / DES
SSL and 2 way SSL (keystore / trustore)
Protecting against Man in the middle fraud
Digital Signature and Certificates

Is there a resource out there that really explains it in a way that doesn't require a Cisco certificate / Linux lingo / know what is subnet masking or other plumbing skills?
