Functions ¶
func CheckPassword ¶
CheckPassword compares the given password against the stored hash. It returns true, if the password is correct.
Example (CorrectPassword) ¶
Example CorrectPassword shows that the bcrypt hashing algorithm can reliably examine whether a given password matches a hash and thus is correct or not.
// Set a really strong password
password := "hello123"
// Generate the bcrypt hash for the password
hash, err := GenerateHash(password)
if err != nil {
fmt.Println(err)
}
// Check that the correct password is recognized
// as the correct password
correct := CheckPassword(hash, password)
fmt.Println(correct)
Output: true
Example (WrongPassword) ¶
Example WrongPassword proves the opposite case passing a wrong password to the CheckPassword function. It is not recognized as correct password and its invalidity is therefore verified.
// Set a really strong password
password := "hello123"
// Generate the bcrypt hash for the password
hash, err := GenerateHash(password)
if err != nil {
fmt.Println(err)
}
// Check the password belonging to the hash with
// a wrong password and verify its invalidity
correct := CheckPassword(hash, "wrong password")
fmt.Println(correct)
Output: false
func GenerateHash ¶
GenerateHash returns a bcrypt hash for the given password. Bcrypt is a very secure hashing algorithm for passwords, which also spares the developer from having to generate a salt on his/her own.
