The ideas of this package have been implemented in the Go's standard library (Go 1.20). It is recommened to use the standard library crypto/ecdh package.

The ECDH key exchange

Elliptic curve Diffie–Hellman (ECDH) is an anonymous key agreement protocol that allows two parties, each having an elliptic curve public–private key pair, to establish a shared secret over an insecure channel.

This package implements a generic interface for ECDH and supports the generic crypto/elliptic and the x/crypto/curve25519 out of the box.

Installation

Install in your GOPATH: go get -u github.com/aead/ecdh
