privateKey, err := rsa.GenerateKey(rand.Reader, 2048) if err != nil { fmt.Println("Failed to generate private key:", err) return // 生成证书模板 certTemplate := x509.Certificate{ SerialNumber: big.NewInt(time.Now().Unix()), Subject: pkix.Name{CommonName: "example.com"}, NotBefore: time.Now(), NotAfter: time.Now().AddDate(1, 0, 0), KeyUsage: x509.KeyUsageDigitalSignature | x509.KeyUsageKeyEncipherment, ExtKeyUsage: []x509.ExtKeyUsage{x509.ExtKeyUsageServerAuth}, DNSNames: []string{"example.com", "www.example.com"}, // 将证书模板序列化为 DER 格式 derBytes, err := x509.CreateCertificate(rand.Reader, &certTemplate, &certTemplate, &privateKey.PublicKey, privateKey) if err != nil { fmt.Println("Failed to create certificate:", err) return // 创建 PEM 编码的证书文件 certOut, err := os.Create("cert.pem") if err != nil { fmt.Println("Failed to create cert.pem:", err) return pem.Encode(certOut, &pem.Block{Type: "CERTIFICATE", Bytes: derBytes}) certOut.Close() fmt.Println("Wrote cert.pem") // 创建 PEM 编码的私钥文件 keyOut, err := os.OpenFile("key.pem", os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0600) if err != nil { fmt.Println("Failed to open key.pem for writing:", err) return pem.Encode(keyOut, &pem.Block{Type: "RSA PRIVATE KEY", Bytes: x509.MarshalPKCS1PrivateKey(privateKey)}) keyOut.Close() fmt.Println("Wrote key.pem")

运行上述代码后,会生成 cert.pem key.pem 两个文件,其中 cert.pem 是 PEM 编码的证书, key.pem 是 PEM 编码的私钥。这些文件可以用于启用 SSL/TLS 加密连接。在实际生产环境中,建议使用更安全的加密算法和密钥长度。
