高分跪求ASP/PHP字符串加密解密或者字符串base64
例如：
原始URL字符串：http://wwww.adfasf.com/upload/20120304/4532524.jpg
我需要将这个字符串加密成：一个很短的字符串，大小写字母+数字或者单独数字或者字母都地。

例：“http://wwww.adfasf.com/upload/20120304/4532524.jpg”=加密后的"afadasfwetqetqwetfasdf"
同时需要解密程序：当我获取到“afadasfwetqetqwetfasdf”时，我通过解密程序得到原始的字符串。

例："afadasfwetqetqwetfasdf"=解密后“http://wwww.adfasf.com/upload/20120304/4532524.jpg”

谢谢，各位大虾。

求程序或者直发：[email protected]

好汉，你自己写个密码算法即可。
这是这样做的，

PHP code

PHP codefunction Valid(){（用户名id*16-32）字符串连上时间与input}<br><font color="#e78608">------解决方案--------------------</font><br>现成的函数不能用吗？<br>

PHP code

$url = "http://wwww.adfasf.com/upload/20120304/4532524.jpg";$encrypt = base64_encode($url);$decrypt = base64_decode($encrypt);echo "encrypt-->>".$encrypt."<br>";//aHR0cDovL3d3d3cuYWRmYXNmLmNvbS91cGxvYWQvMjAxMjAzMDQvNDUzMjUyNC5qcGc=echo "decrypt-->>".$decrypt."<br>";//http://wwww.adfasf.com/upload/20120304/4532524.jpg<div class="clear">
                 
              
              
        
            </div>
