Constants

const KeyLen = 32

KeyLen is the encryption key length

Variables

var ErrDigest = errors.New("value does not have correct digest")

ErrDigest signals a checksum mismatch

Functions

func Decrypt

func Decrypt(e, expected_sha256 string, key []byte) (string, error)

Decrypt reverses Encrypt e is the crypted+encoded string

MakeKey is the best way to derive a key

func DerivePassword

func DerivePassword(password string, cfg argon2.Config) (string, error)

DerivePassword performs a one-way hash on a password using argon2

func EncodedSHA256

func EncodedSHA256(s string) string

EncodedSHA256 returns the encoded (base16) sha256sums

func Encrypt

func Encrypt(s string, key []byte) (string, error)

Encrypt returns the hex-encoded AES symmetric encryption of s with key

MakeKey is the best way to derive a key

func MakeKey

func MakeKey(s string) ([]byte, error)

MakeKey returns a 32-len byte

func VerifyPassword

func VerifyPassword(guess, derived string) (bool, error)

VerifyPassword returns true if guess is the same as the password forming derived
