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.") }}
