type Cipher ¶
A Cipher is an instance of RC4 using a particular key.
type Cipher struct {
// contains filtered or unexported fields
}
func NewCipher ¶
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 ¶
func (c *Cipher) Reset()
Reset zeros the key data and makes the Cipher unusable.
Deprecated: Reset can't guarantee that the key will be entirely removed from the process's memory.
func (*Cipher) XORKeyStream ¶
func (c *Cipher) XORKeyStream(dst, src []byte)
XORKeyStream sets dst to the result of XORing src with the key stream. Dst and src must overlap entirely or not at all.
type KeySizeError ¶
type KeySizeError int
func (KeySizeError) Error ¶
func (k KeySizeError) Error() string
