Overview

Package rc4 提供 RC4 流密码工具。RC4 已不安全， 仅为兼容旧系统保留，勿用于新系统。

Functions

func Apply

func Apply(key string, src []byte) ([]byte, error)

Apply 使用 RC4 对输入执行一次流变换，返回新的结果切片. RC4 是对称流密码，加密与解密是同一操作，统一用 Apply。

func ApplyInPlace

func ApplyInPlace(key string, buf []byte) error

ApplyInPlace 使用 RC4 对输入执行一次流变换，并原地写回结果.

func DecryptBase64ToString

func DecryptBase64ToString(key, cipherText string) (string, error)

DecryptBase64ToString 解码 Base64 后执行 RC4 解密并返回字符串.

func DecryptFromBase64

func DecryptFromBase64(key, cipherText string) ([]byte, error)

DecryptFromBase64 解码 Base64 后执行 RC4 解密.

func EncryptStringToBase64

func EncryptStringToBase64(key, plainText string) (string, error)

EncryptStringToBase64 使用 RC4 加密字符串并编码为 Base64.

Example

package main

import (
	"fmt"

	"github.com/gtkit/encryx/rc4"
)

func main() {
	const key = "secret-key"
	enc, err := rc4.EncryptStringToBase64(key, "hello-rc4")
	if err != nil {
		panic(err)
	}
	dec, err := rc4.DecryptBase64ToString(key, enc)
	if err != nil {
		panic(err)
	}
	fmt.Println(dec)
}

Output:
hello-rc4

func EncryptToBase64

func EncryptToBase64(key string, plainText []byte) (string, error)

EncryptToBase64 使用 RC4 加密并编码为 Base64.
