php 单向散列加密
1.加密文件
- <?php
- //sha1_en.php
- header("content-type:text/html;charset=utf-8");
- $str = "我是张三,能给我个人数据吗";
- $salt="123456";//我是唯一不变的salt
- $sha1=sha1($str.$salt);//或者$sha1=md5($str.$salt);
- echo $str;
- echo "<br/>";
- echo $sha1;
- echo "<br/>";
- echo "http://localhost//sha1_de.php?str=$str&sha1=$sha1";
- ?>
2.解密文件
- <?php
- //sha1_de.php
- header("content-type:text/html;charset=utf-8");
- $str=$_GET["str"];
- $sha1=$_GET["sha1"];
- $salt="123456";//我是唯一不变的salt
- $verify=sha1($str.$salt);//或者$verify=md5($str.$salt);
- echo $verify;
- if($verify==$sha1){
- echo "你是张三,给你信息";
- }else{
- echo "你是假冒伪劣产品";
- echo "你的ip".$_SERVER['REMOTE_ADDR']."已经被记录了";
- }
- ?>
