Energon

Energon is a traits contract that resolves the power of cryptographic libraries (inputs) into a single generalized API (output). Inspired by Kyber

Concept

• Inputs specified at compile time via feature flag(s) may be selected based on supported architectures, performance, or other considerations.
• Output need to be combined into a Scheme trait to perform static dispatch, e.g. Drand Scheme
