javascript加密与解密

2022-07-15 80酷酷网 80kuku.com

　　javascript|加密|解密

javascript加密主要有JScript.Encode加密方式跟escape方式.

加密的用处主要有:1.隐藏自己的js代码,或者阻止他人使用自己的js成果.这方面在网页木马里面尤其使用的多.

2.阻止别人盗链.现在很多宽频网站或者网络电视网站,由于没有使用drm保护,

他们只能通过保护url地址来防止别人直接打开mms或者http地址.故而需要加密地址.这个现在的qq直播网站,sina,sohu的宽频都是这样.不过都是可以破解的.

因为js再怎么加密最终ie重要能解释的.

方法1.

javascript:s=document.documentElement.outerHTML;document.write('<body></body>');document.body.innerText=s;

这段代码拷入ie地址栏(注意首先要打开你觉得加密的网址,然后覆盖这个网址在ie输入上面代码)

方法2.

找到JScript.Encode加密以后的代码.直接将下面代码拷入一个html中
