Types

type Cipher

type Cipher struct {
	// contains filtered or unexported fields
}

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

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 deprecated

This method has been deprecated.
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
