Package rc4
Package rc4 implements RC4 encryption, as defined in Bruce Schneier's
Applied Cryptography.
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls—perhaps dynamically.
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring func
token.
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.
type Cipher struct {
}
A Cipher is an instance of RC4 using a particular key.
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 (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 int
func (KeySizeError) Error
func (k KeySizeError) Error() string
Bugs
- ☞ RC4 is in common use but has design weaknesses that make
it a poor choice for new protocols.
