Functions

func FixedXOR

func FixedXOR(h1, h2 string) (string, error)

FixedXOR does bitwise XOR of two hex strings. The strings must be of equal length. (Set 1, challenge 2.)

func HexToBase64

func HexToBase64(h string) (string, error)

HexToBase64 decodes hex string into base64 string. (Set 1, challenge 1.)
