Todaygo

// This program demonstrates that the updated crypto/tls package compiles
// and can create a TLS configuration. It does not perform network I/O.
package main

import (
	"crypto/tls"
	"fmt"
)

func main() {
	// Create a TLS configuration that skips certificate verification
	// for demonstration purposes. In production, use InsecureSkipVerify: false.
	cfg := &tls.Config{InsecureSkipVerify: true}

	// Print the configuration to show it was constructed successfully.
	fmt.Printf("TLS config created: %+v\n", cfg)
}

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
