ECDH
This is a go implementation of elliptical curve diffie-hellman key exchange method.
It supports the NIST curves (and any curves using the elliptic.Curve go interface)
as well as djb's curve25519.
The library handles generating of keys, generating a shared secret, and the (un)marshalling of the elliptical curve keys into slices of bytes.
Warning and Disclaimer
I am not a cryptographer, this was written as part of a personal project to learn about cryptographic systems and protocols. No claims as to the security of this library are made, I would not advise using it for anything that requires any level of security. Pull requests or issues about security flaws are however still welcome.
Compatibility
Works with go 1.2 onwards.
TODO
- Improve documentation

Types ¶
type ECDH ¶
type ECDH interface {
GenerateKey(io.Reader) (crypto.PrivateKey, crypto.PublicKey, error)
Marshal(crypto.PublicKey) []byte
MarshalPrivateKey(crypto.PrivateKey) []byte
Unmarshal([]byte) (crypto.PublicKey, bool)
UnmarshalPrivateKey(data []byte) crypto.PrivateKey
}
The main interface for ECDH key exchange.
func NewCurve25519ECDH ¶
func NewCurve25519ECDH() ECDH
NewCurve25519ECDH creates a new ECDH instance that uses djb's curve25519 elliptical curve.
func NewEllipticECDH ¶
NewEllipticECDH creates a new instance of ECDH with the given elliptic.Curve curve to use as the elliptical curve for elliptical curve diffie-hellman.
