How to hash and compare passwords in Go

The best to hash passwords in Go is using golang.org/x/crypto/bcrypt: func HashPassword(password string) (string, error) { bytes, err := bcrypt.GenerateFromPassword([]byte(password), bcrypt.DefaultCost) return string(bytes), err } func CheckPasswordHash(password, hash string) bool { err := bcrypt.CompareHashAndPassword([]byte(hash), []byte(password)) return err == nil } You should use the default bcrypt.DefaultCost just in case that the current value will become not sufficient and the default cost will increase.
