Code Snippet (optional)
package main
import (
"crypto/sha256"
"crypto/subtle"
"github.com/gofiber/fiber/v3"
"github.com/gofiber/fiber/v3/middleware/keyauth"
)
const (
apiKey = "my-super-secret-key"
)
func main() {
app := fiber.New()
authMiddleware := keyauth.New(keyauth.Config{
Validator: func(c fiber.Ctx, key string) (bool, error) {
hashedAPIKey := sha256.Sum256([]byte(apiKey))
hashedKey := sha256.Sum256([]byte(key))
if subtle.ConstantTimeCompare(hashedAPIKey[:], hashedKey[:]) == 1 {
return true, nil
}
return false, keyauth.ErrMissingOrMalformedAPIKey
},
})
app.Get("/", func(c fiber.Ctx) error {
return c.SendString("Welcome")
})
app.Get("/allowed", authMiddleware, func(c fiber.Ctx) error {
return c.SendString("Successfully authenticated!")
})
app.Listen(":3000")
