Detailed Description

Key agreement algorithms based on elliptic curves.

A key agreement algorithm generates a shared secret key, in a way that both parties contribute to its creation, and that make it hard for an outside observer to determine the key.

There are mainly three groups of algorithms: those based on the NIST standard secpXXX curves (P-256 etc.), those based on Montgomery curves, and those based on module-learning with errors. The latter are often referred to as KEM (key encapsulation mechanisms) algorithms and are quantum-resistant.
