package circl
import "github.com/cloudflare/circl"
Package circl provides a collection of cryptographic primitives. The goal of this module is to be used as a tool for experimental deployment of cryptographic algorithms targeting Post-Quantum (PQ) and Elliptic Curve Cryptography (ECC).
Following blog post describes ideas behind CIRCL in more details: https://blog.cloudflare.com/introducing-circl/
