我们常常看到类似新浪上面的视频播放页面源文件是一堆乱码，实际上是经过JScript加密过的代码，这样可以防止普通用户轻易的找到视频源文件地址，从而盗链，下面把JScript加密解密的方法整理了一下：

JScript.encode实现加密解密的脚本代码如下：

上面代码的使用方法如下：
1、建一个.htm的文件，加入上面的代码。
2、再后面写上：
<form name="form">
<TEXTAREA NAME="code" ROWS="20" COLS="40" onfocus=this.select()>在这里写入你要加密或解密的内容。</TEXTAREA><BR>
<INPUT TYPE="button" value="/JScript.encode加密" onclick="this.form.code.value="/screncode(this.form.code.value,"'JS')">
<INPUT TYPE="button" value="/JScript.encode解密" onclick="this.form.code.value="/strdec(this.form.code.value)"">
</form>
<TEXTAREA NAME="code" ROWS="20" COLS="40" onfocus=this.select()>在这里写入你要加密或解密的内容。</TEXTAREA><BR>
<INPUT TYPE="button" value="/JScript.encode加密" onclick="this.form.code.value="/screncode(this.form.code.value,"'JS')">
<INPUT TYPE="button" value="/JScript.encode解密" onclick="this.form.code.value="/strdec(this.form.code.value)"">
</form>
3、保存该文件，用浏览器打开就可以进行加密和解密了。
下面有一个我做好的在线可以直接使用的页面，大家可以直接访问进行加密解密：

不能加密
这段代码不能解全，请问有什么更好的办法呢？

为什么只能解密，不能加密呢？这段程序代码有问题吗？
好像跟你浏览器或者系统上是否有一个控件有关系，具体的我也得研究研究:(

太复杂了,呵呵!
Excellent post. Keep posting such kind of information on your page.
Im really impressed by it.
Hello there, You have done an incredible job.
I’ll definitely digg it and in my view recommend to my friends.
I’m sure they’ll be benefited from this website.
Great post.
WOW just what I was looking for. Came here by searching
for minecraft free download 2018
You really make it seem so easy with your presentation but I find this topic to be really
something that I think I would never understand. It seems too
complex and very broad for me. I am looking forward for your
next post, I will try to get the hang of it!
My spouse and I absolutely love your blog and find almost all of your post’s
to be just what I’m looking for. Would you offer guest writers to write content for you personally?
I wouldn’t mind publishing a post or elaborating on some of
the subjects you write with regards to here. Again, awesome
web log!
I relish, result in I found just what I was looking for.
You have ended my 4 day lengthy hunt! God Bless you man. Have a great day.
Bye
It’s appropriate time to make some plans for the future and it is time
to be happy. I have learn this submit and if I may I want to counsel you some attention-grabbing things or
tips. Maybe you can write next articles regarding this article.
I wish to learn even more issues approximately it!
I know this if off topic but I’m looking into starting my own blog
and was wondering what all is needed to get set up? I’m assuming
having a blog like yours would cost a pretty penny?
I’m not very web smart so I’m not 100% positive. Any recommendations or advice would be greatly appreciated.
Appreciate it
Ahaa, its nice conversation about this paragraph here at this web site, I have read all that, so now me also commenting at this place.
If you are going for finest contents like I do, only go to see this site all the time since it
presents feature contents, thanks
This is a topic which is near to my heart… Thank you!
Where are your contact details though?
Good way of telling, and fastidious piece of writing to obtain facts concerning my presentation subject,
which i am going to present in school.
Hi there! I know this is kind of off-topic but I had to ask.
Does managing a well-established website such as yours take a
massive amount work? I’m brand new to running a blog but I do write in my diary on a daily basis.
I’d like to start a blog so I will be able to share my own experience and thoughts online.
Please let me know if you have any suggestions or tips for
brand new aspiring blog owners. Thankyou!
