Functions

func Decrypt

func Decrypt(src, key []byte) ([]byte, error)

Decrypt decrypts the first block in src into dst. Dst and src may point at the same memory.

Example

tt := rc4Tests[0]
dst, _ := rc4.Decrypt(tt.out, tt.key)
fmt.Println(bytes.Compare(tt.in, dst))

Output:

0

func DecryptHex

func DecryptHex(src, key string) (string, error)

DecryptHex decrypts the first block in src into dst.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/rc4"
)

func main() {
	dst, _ := rc4.DecryptHex("6c034d94", "key")
	fmt.Println(dst)

}

Output:

goyy

func Encrypt

func Encrypt(src, key []byte) ([]byte, error)

Encrypt encrypts the first block in src into dst. Dst and src may point at the same memory.

Example

tt := rc4Tests[0]
dst, _ := rc4.Encrypt(tt.in, tt.key)
fmt.Println(bytes.Compare(tt.out, dst))

Output:

0

func EncryptHex

func EncryptHex(src, key string) (string, error)

EncryptHex encrypts the first block in src into dst.

Example

package main

import (
	"fmt"

	"gopkg.in/goyy/goyy.v0/util/crypto/rc4"
)

func main() {
	dst, _ := rc4.EncryptHex("goyy", "key")
	fmt.Println(dst)

}

Output:

6c034d94
