Types

type BCryptHasher

type BCryptHasher struct {
	// contains filtered or unexported fields
}

BCryptHasher hasher that use BCrypt algorithm to secure password.

func (BCryptHasher) Compare

func (bh BCryptHasher) Compare(hashedPassword, plainPassword []byte) bool

Compare implements Hasher interface.

func (BCryptHasher) Hash

func (bh BCryptHasher) Hash(plainPassword []byte) ([]byte, error)

Hash implements Hasher interface.

type Hasher

type Hasher interface {
	Hash([]byte) ([]byte, error)
	Compare([]byte, []byte) bool
}

Hasher define set of methods that object needs to implement to be considered as a hasher.

func NewBCryptHasher

func NewBCryptHasher(cost int) (Hasher, error)

NewBCryptHasher allocates new NewBCryptHasher. If cost is not between min and max value it returns an error.
