Cryptography has mailing lists, and hobbyists, and open source influences, and IRC channels. You, as a rank beginner, are not going to get to a level where you can design a crypto scheme that a dilletante hobbyist with the equivalent of a few university courses, and a lot of time can’t beat. Not in a few days, probably not even if you’re Terry Tao.
I disagree. It’s actually remarkably easy to create for all intents and purposes (barring the resolution of several outstanding problems in cryptography and computer science) impossible-to-break cryptography schemes if you know anything about RSA, lattice methods, etc.
Unless “a lot of time” means the age of the universe (precluding functional quantum computers before then).
That needs an expert cryptanalyst. Those guys tend to be busy.

I see a lot of broken systems designed by people who’ve read Applied Cryptography.
