Constants

const (
	Size int = 2 // size of the header in bytes

	EncryptionMethod_RSA_2048_with_AES_256_CBC byte = 0x01
)

Types

type Header

type Header struct {
	Version          uint8
	IsRequest        bool
	EncryptionMethod byte
}

func Decode

func Decode(data []byte) (Header, error)

Converts the inputted byte slice to a header if properly formatted. Otherwise we will return an error. The function will check the version strictly, meaning that if it does not match exactly we will return an error.

func (*Header) Encode

func (header *Header) Encode() ([]byte, error)

Encodes the header struct into a byte slice. If the header version specified is larger than the one specified in the source return an error. Checks that the encryption method is supported as well otherwise return an error.
