Overview ▾

Package rc4 implements RC4 encryption, as defined in Bruce Schneier's Applied Cryptography.

RC4 is cryptographically broken and should not be used for secure applications.

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 so that it will no longer appear in 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 may be the same slice but otherwise should not overlap.

type KeySizeError

type KeySizeError int

func (KeySizeError) Error

func (k KeySizeError) Error() string
