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/hurae/ecdh

Difference:

• always return a []byte type public key
• use non-deprecated new X25519 API.
• implement Check for Curve25519, just the same check inside golang.org/x/crypto/curve25519. That means length 32 and not all zero.
• ComputeSecret will now pass the error which golang.org/x/crypto/curve25519 gives out.
