上面打错一个字：“要在影片本身上做文字”＝“要在影片本身上做文章”，也就是“加密”影片本身，wmv是什么许可证，rmvb忘了，反正搜索多得是

在地址上加密基本上是没用的，要在影片本身上做文字，wmv和rmvb都有各自的处理方式，网上资料多，搜索即可

........加密...
你可以用可逆算法... sha1, baseX, uuendoe, des, .... 等加密后, 转义为 url 编码
然后 再 解码 url, 再解码 x算法...

在客户端脚本基本谈不上加密解密
因为你加密的算法你的客户也知道
理想的方法是把加密用的函数混淆下，防止函数暴露

静态页面加密？？？ 基本上是没法做到真正保密的哦，给你个base64加密解密的方法
你自己提出来用吧
