Use crypto/tls to create secure connections by wrapping a net.Conn with tls.Client or tls.Server and a tls.Config.

Use the crypto/tls package to create secure TLS connections by configuring a tls.Config and wrapping a network connection with tls.Client or tls.Server.

import "crypto/tls"

conn, err := tls.Dial("tcp", "example.com:443", &tls.Config{})
if err != nil {
    // handle error
}
// use conn as a net.Conn
  1. Import the package and define a tls.Config with your security settings.
  2. Wrap your network connection using tls.Client for clients or tls.Server for servers.
  3. Perform I/O on the returned net.Conn just like a standard connection.
