How to hash a string using SHA-1 in Go?

To hash a string using SHA-1 in Go, you can use the crypto/sha1 package. Here's an example code that demonstrates how to hash a string using SHA-1:

package main

import (
	"crypto/sha1"
	"fmt"
)

func main() {
	str := "Hello, World!"

	// Create a new SHA-1 hasher
	hasher := sha1.New()

	// Write the string to the hasher
	hasher.Write([]byte(str))

	// Get the hashed result as a byte slice
	hashedBytes := hasher.Sum(nil)

	// Convert the hashed bytes to a hexadecimal string
	hashedStr := fmt.Sprintf("%x", hashedBytes)

	fmt.Println("Hashed String:", hashedStr)
}

This code example will output:

Hashed String: 0a4d55a8d778e5022fab701977c5d840bbc486d0

In this code, we first import the crypto/sha1 package. We then create a new SHA-1 hasher using sha1.New(). The Write() method is used to write the string to the hasher. After writing the string, we get the hashed result as a byte slice using Sum(nil). Finally, we convert the byte slice to a hexadecimal string using fmt.Sprintf("%x", hashedBytes).
