How to Use Elliptic Curve Diffie Hellman Library in Go

Mon, 18 May 2026 23:15:32 +0530

Go introduced a new library called Elliptic Curve Diffie Hellman(crypto/ecdh) in v1.20.

Let’s see how to use this library to exchange encrypted data between two entities without sharing the secret that was used to encrypt the data.

Generate public key on the client

clientCurve := ecdh.P256()
clientPrivKey, err := clientCurve.GenerateKey(rand.Reader)
if err != nil {
	t.Fatalf("Error: %v", err)
}
clientPubKey := clientPrivKey.PublicKey()

Generate public key on the server

serverCurve := ecdh.P256()
serverPrivKey, err := serverCurve.GenerateKey(rand.Reader)
if err != nil {
	t.Fatalf("Error: %v", err)
}
serverPubKey := serverPrivKey.PublicKey()

The clientPubkey and serverPubKey can be shared over the network as plain text.
