Functions

func PadEncrypted

func PadEncrypted(header []byte) ([]byte, error)

Types

type Header

type Header struct {
	Version  string
	Category string
	Label    string

	// Path of the privage file containing the header
	Path string

	// Error when unpadding or decrypting the header of the  file
	Err error
}

A Header contains the filename and a category (the metadata) of a file.

This metadata is serialized and encrypted at the start of a privage file.

func Parse

func Parse(h []byte) *Header

Parse parses a serialized version of a header and creates a Header struct

func (*Header) Pad

func (h *Header) Pad() []byte

Pad returns a serialized version of the header: string concatenation with padding

func (*Header) String

func (h *Header) String() string
