Functions ¶

func CompareHashAndPassword ¶

func CompareHashAndPassword(encoded []byte, password []byte) error

CompareHashAndPassword compares an argon2id hashed and encoded password with its possible plaintext equivalent. Returns nil on success, or an error on failure.

func GenerateFromPassword ¶

func GenerateFromPassword(password []byte) ([]byte, error)

GenerateFromPassword generates a new argon2id encoded hash from the specified password

func GenerateFromPasswordWithParams ¶

func GenerateFromPasswordWithParams(password []byte, params IDParams) ([]byte, error)

GenerateFromPasswordWithParams generates a new argon2id encoded hash from the specified password using the parameters specified

func GenerateFromPasswordWithParamsAndSalt ¶

func GenerateFromPasswordWithParamsAndSalt(password []byte, params IDParams, salt []byte) ([]byte, error)

GenerateFromPasswordWithParamsAndSalt generates a new argon2id encoded hash from the specified password and salt using the parameters specified

func GenerateRandomBytes ¶

func GenerateRandomBytes(size uint32) ([]byte, error)

GenerateRandomBytes generates random bytes of the specified size

Types ¶

type IDParams ¶

type IDParams struct {
	SaltLength  uint32
	Iterations  uint32
	Memory      uint32
	Parallelism uint8
	KeyLength   uint32
}

IDParams holds all necessary parameters to configure argon2id

var DefaultParams IDParams

DefaultParams holds resonable default parameters for argon2id
