type CipherSource
A Cipher is an instance of RC4 using a particular key.
type Cipher struct { // contains filtered or unexported fields }
func NewCipherSource
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) ResetSource
func (c *Cipher) Reset()
Reset zeros the key data so that it will no longer appear in the process's memory.
func (*Cipher) XORKeyStreamSource
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 KeySizeErrorSource
type KeySizeError int
func (KeySizeError) ErrorSource
func (k KeySizeError) Error() string

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