Go语言如何实现AzDG可逆加密算法实例

本文实例讲述了Go语言实现AzDG可逆加密算法。分享给大家供大家参考。具体实现方法如下：

package main

import (

"fmt"

"crypto/md5"

"encoding/base64"

"time"

)
var cipher = "密鑰"

var h = md5.New()
func cipherEncode(sourceText string) string {

h.Write([]byte(cipher))

cipherHash := fmt.Sprintf("%x", h.Sum(nil))

h.Reset()

inputData := []byte(sourceText)

loopCount := len(inputData)

outData := make([]byte,loopCount)

for i:= 0; i < loopCount ; i++ {

outData[i] = inputData[i] ^ cipherHash[i%32]

}

return fmt.Sprintf("%s", outData)

}
func encode(sourceText string) string {

h.Write([]byte(time.Now().Format("2006-01-02 15:04:05")))

noise := fmt.Sprintf("%x", h.Sum(nil))

h.Reset()

inputData := []byte(sourceText)

loopCount := len(inputData)

outData := make([]byte,loopCount*2)



for i, j := 0,0; i < loopCount ; i,j = i+1,j+1 {

outData[j] = noise[i%32]

j++

outData[j] = inputData[i] ^ noise[i%32]

}



return base64.StdEncoding.EncodeToString([]byte(cipherEncode(fmt.Sprintf("%s", outData))))

}
func decode(sourceText string) string {

buf, err := base64.StdEncoding.DecodeString(sourceText)

if err != nil {

fmt.Println("Decode(%q) failed: %v", sourceText, err)

return ""

}

inputData := []byte(cipherEncode(fmt.Sprintf("%s", buf)))

loopCount := len(inputData)

outData := make([]byte,loopCount)

for i, j := 0,0; i < loopCount ; i,j = i+2,j+1 {

outData[j] = inputData[i] ^ inputData[i+1]

}

return fmt.Sprintf("%s", outData)

}
func main() {

 s := encode("張學友")

fmt.Println(s)

fmt.Println(decode(s))

}
