type Cipher Uses

type Cipher struct {
    // contains filtered or unexported fields

A Cipher is an instance of RC4 using a particular key.

func NewCipher Uses

func NewCipher(key []byte) (*Cipher, error)

NewCipher creates and returns a new Cipher. The key argument should be the RC4 key, at least 1 byte and at most 256 bytes.

func (*Cipher) Reset Uses

func (c *Cipher) Reset()

Reset zeros the key data so that it will no longer appear in the process's memory.

func (*Cipher) XORKeyStream Uses

func (c *Cipher) XORKeyStream(dst, src []byte)

XORKeyStream sets dst to the result of XORing src with the key stream. Dst and src may be the same slice but otherwise should not overlap.

type KeySizeError Uses

type KeySizeError int

func (KeySizeError) Error Uses

func (k KeySizeError) Error() string


RC4 is in common use but has design weaknesses that make it a poor choice for new protocols.
