A safe rule of thumb with crypto code / libraries: If the thought of writing that type of code doesn't scare you for at least a dozen or so reasons, you don't know enough to tread in that playground. Or you're one of the damned few people on the planet qualified and are already working on one.
The best way to become one of these damned few people is getting started though.
No need to scare the newcomers off. Everyone was a newcomer once.
