这是一个代码示例,演示了 Go 中密钥的编码和解码。知道您需要连接几个步骤会有所帮助。加密算法是第一步,在这种情况下是 ECDSA 密钥。然后你需要标准编码,x509 是最常用的标准。最后你需要一种文件格式,PEM 又是一种常用的格式。这是目前最常用的组合,但可以随意替换任何其他算法或编码。
func encode(privateKey *ecdsa.PrivateKey, publicKey *ecdsa.PublicKey) (string, string) {
x509Encoded, _ := x509.MarshalECPrivateKey(privateKey)
pemEncoded := pem.EncodeToMemory(&pem.Block{Type: "PRIVATE KEY", Bytes: x509Encoded})
x509EncodedPub, _ := x509.MarshalPKIXPublicKey(publicKey)
pemEncodedPub := pem.EncodeToMemory(&pem.Block{Type: "PUBLIC KEY", Bytes: x509EncodedPub})
return string(pemEncoded), string(pemEncodedPub)
}
func decode(pemEncoded string, pemEncodedPub string) (*ecdsa.PrivateKey, *ecdsa.PublicKey) {
block, _ := pem.Decode([]byte(pemEncoded))
x509Encoded := block.Bytes
privateKey, _ := x509.ParseECPrivateKey(x509Encoded)
blockPub, _ := pem.Decode([]byte(pemEncodedPub))
x509EncodedPub := blockPub.Bytes
genericPublicKey, _ := x509.ParsePKIXPublicKey(x509EncodedPub)
publicKey := genericPublicKey.(*ecdsa.PublicKey)
return privateKey, publicKey
}
func test() {
privateKey, _ := ecdsa.GenerateKey(elliptic.P384(), rand.Reader)
publicKey := &privateKey.PublicKey
encPriv, encPub := encode(privateKey, publicKey)
fmt.Println(encPriv)
fmt.Println(encPub)
priv2, pub2 := decode(encPriv, encPub)
if !reflect.DeepEqual(privateKey, priv2) {
fmt.Println("Private keys do not match.")
}
if !reflect.DeepEqual(publicKey, pub2) {
fmt.Println("Public keys do not match.")
}
}
