In [[cryptography]], a [[key exchange|public key exchange]] algorithm is a [[cryptographic algorithm]] which allows two parties to create and share a secret key, which they can use to encrypt messages between themselves. The '''[[ring learning with errors]] key exchange''' ('''RLWE-KEX''') is one of a new class of public key exchange algorithms that are designed to be secure against an adversary that possesses a [[quantum computer]]. This is important because
