type Authenticator ¶

type Authenticator interface {
	Compare(hash, plaintext string) error
	Hash(plaintext string) (string, error)
}

Authenticator is the interface that wraps password authentication utilities.

Compare performs a constant time comparison of the given plaintext and hash using the authenticators underlying key derivation function. It returns nil if and only if password is the hash's plaintext equivalent.

Hash hashes the given plaintext using the authenticator's underlying key derivation function.
