Nobody in their right minds would create a "roll-your-own-crypto" after reading a copy of Applied Cryptography or any other book for that matter, and expect to make something awesome.
When somebody who aren't idiots actually trusts what they've created in this area of work, I tend to assume that it's at least worth checking out as this requires insane efforts as you're obviously well aware of yourself.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
