type ARC ¶

type ARC struct {
	Rgen PRGA
	// contains filtered or unexported fields
}

ARC is the stucture that holds the vital components for a valid RC4 implementation Including a pointer to a PRGA (Psuedo Random Generation Algorithm)

func (a *ARC) Decode(p_stream *bufio.Reader) []byte

func (a *ARC) Encode(p_stream *bufio.Reader) []byte

func (a *ARC) Init(key_ []byte, iv_ ...[]byte)

func (a *ARC) WriteEncFile(cyphertext []byte, name string) error

type PRGA ¶

type PRGA struct {
	S [256]byte
	// contains filtered or unexported fields
}

func (a *ARC) ReadEncFile(cyphertext []byte, name string) (byte[10], error) {
  //parses a CypherSabre file (has extension .cs1)
  //The IV removed and returned as a byte array
  //The remaining cyphertext is copied into the cyphertext buffer
}

PRGA is the Psuedo Rando Generation Algorithm it contains: two single byte indexes and a 256 byte state array

func (gen *PRGA) KSA(key [256]byte, keylen uint8)

func (gen *PRGA) Kstream() byte
