Types

type ECDH

type ECDH interface {
	GenerateKey(io.Reader) (crypto.PrivateKey, crypto.PublicKey, error)
	Marshal(crypto.PublicKey) []byte
	Unmarshal([]byte) (crypto.PublicKey, bool)
	GenerateSharedSecret(crypto.PrivateKey, crypto.PublicKey) ([]byte, error)
}

ECDH 秘钥交换算法的主接口

func NewCurve25519ECDH

func NewCurve25519ECDH() ECDH

NewCurve25519ECDH 使用密码学家Daniel J. Bernstein的椭圆曲线算法:Curve25519来创建ECDH实例 因为Curve25519独立于NIST之外, 没在标准库实现, 需要单独为期实现一套接口来支持ECDH

func NewEllipticECDH

func NewEllipticECDH(curve elliptic.Curve) ECDH

NewEllipticECDH 指定一种椭圆曲线算法用于创建一个ECDH的实例 关于椭圆曲线算法标准库里面实现了4种: 见crypto/elliptic
