Various errors returned by the library

func Key Uses

func Key(password, salt []byte, iterations, parallelism, memory uint32, keyLength int, variant Variant) ([]byte, error)

Key derives an Argon2(i|d) hash from the input.

type Variant Uses

type Variant uint8

Variant is the type of algorithm to use

const (
    Argon2d Variant = iota

Argon2i uses data-derived pseudorandom numbers, protecting from side-channel attacks.
