Go语言实现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：

　　复制代码 代码如下: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))
}

　　希望本文所述对大家的Go语言程序设计有所帮助。
