Functions

func Cipher

func Cipher(payload []byte, mask [4]byte, offset int)

Cipher applies XOR cipher to the payload using mask. Offset is used to cipher chunked data (e.g. in io.Reader implementations).

To convert masked data into unmasked data, or vice versa, the following algorithm is applied. The same algorithm applies regardless of the direction of the translation, e.g., the same steps are applied to mask the data as to unmask the data.

func MaskXOR

func MaskXOR(b []byte, key []byte)
