1.加密文件
<?php

$str = "我是张3,能给我个人数据吗";
$salt="123456";//我是唯1不变的salt
$sha1=sha1($str.$salt);//或$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=utf⑻");
$str=$_GET["str"];
$sha1=$_GET["sha1"];
$salt="123456";//我是唯1不变的salt
$verify=sha1($str.$salt);//或$verify=md5($str.$salt);
echo $verify;
if($verify==$sha1){
echo "你是张3,给你信息";
}else{
echo "你是假冒伪劣产品";
