I am completely and totally altering my budget. My family and I do ok for ourselves...

I am learning the need for safe data storage/ Hosting and internet traffic infrastructure. I hate seeing what's become of my country... what path do I need to take to dedicate my education to Cryptography and things of the like?

I am medically retired from the US Army, Started an R&D Firm, I am a very quick learner of any theory... What's puzzling me is where to start at, and what to graduate to once I have learned all the languages? I am currently learning dependencies in Python... I have a REMARKABLE amount of time on my hands and all I do is learn... guidance input please?
