> what I am saying is that "Don't roll your own crypto" mono-culture makes impossible for people to grasp the basics of crypto. It's not. People not wanting to learn cryptography systematically make impossible for themselves to grasp the basics of crypto. There are a lot of topics to be covered, which goes way, way beyond encrypting stuff. People dabbling with making their own cipher or implementing DES on their own would learn exactly nothing of the cryptography. You really need to be shown a lot of stuff to understand where the industry and research were decades ago, much less where they are now, and you can't really learn that on your own, you need a guide to show you where your knowledge is still lacking.
