How can I implement user authentication in Go?

You can implement user authentication in Go using packages like 'gorilla/sessions' for session management and 'golang.org/x/crypto/bcrypt' for password hashing.

What are the steps to set up session management?

First, install the 'gorilla/sessions' package. Then, create a session store and use it to manage user sessions in your handlers.

How do I hash passwords securely?

You can use the 'bcrypt' package. Use 'bcrypt.GenerateFromPassword' to hash the password and 'bcrypt.CompareHashAndPassword' to verify it.

Can you show me a code example?

Sure! Here's a simple example:

package main

import (
    "golang.org/x/crypto/bcrypt"
    "github.com/gorilla/sessions"
)

// Hashing a password
func hashPassword(password string) (string, error) {
    bytes, err := bcrypt.GenerateFromPassword([]byte(password), 14)
    return string(bytes), err
}

// Verifying a password
func verifyPassword(hashedPassword, password string) error {
    return bcrypt.CompareHashAndPassword([]byte(hashedPassword), []byte(password))
}

This code hashes a password and verifies it.
