网页加密与跳转
实现办法:
十年的利川网站建设经验,针对设计、前端、开发、售后、文案、推广等六对一服务,响应快,48小时及时工作处理。营销型网站建设的优势是能够根据用户设备显示端的尺寸不同,自动调整利川建站的显示方式,使网站能够适用不同显示终端,在浏览器中调整网站的宽度,无论在任何一种浏览器上浏览网站,都能展现优雅布局与设计,从而大程度地提升浏览体验。创新互联从事“利川网站设计”,“利川网站推广”以来,每个客户项目都认真落实执行。
(1)利用弹出窗口封锁鼠标右键将下面这段代码放在网页HTML代码的标志中,就可以实现封锁右键,给网页加密。
(2)弹出“添加收藏夹”封锁鼠标右键将下面这段代码放在网页的HTML代码的标志中。实现点击右键出现“添加到收藏夹”选项。
(3)彻底封锁鼠标右键将下面这段代码放在网页的HTML代码的标志中能够实现彻底封锁鼠标右键的效果,由于这个脚本在右键按下时调用一个函数,所以可以改为很多种类型。即使按下左键,再按下右键,放开左键,再放开右键的方法也还是破解不了。
(4)禁止查看源文件将下面这段代码放在网页的HTML代码的标志中则可以实现禁止利用IE浏览器查看源文件。
(5)用乱码显示链接、调用地址加密。利用某些函数把URL字符转换成ASCII码,从而达到隐藏链接Frame页面和*.js,*.asp等脚本的目的。返回ASCII码escape(character),ASCII码为%XX格式,XX是十六进制,如空格键为%20。返回字符unEscape(string)。
如何在前端调用js对密码进行加密
加密和解密原则上都应该在后台完成才合乎常理,如果在前端加密,就好比在众目睽睽之下化妆易容,然后声称自己是另一个人一样,没意义啊。
如果一定要在前端加密,可以这样:
input type="submit" name="submit" value="注册" onclick="var pwd=document.getElementsByName('password')[0];pwd.value=md5(pwd.value);"/
Jquery与java MD5加密不同

这是javascript的md5算法,测试过跟java的MD5加出来是一样的
使用方法:
var md5Pwd = encryptToMD5(str);
用jQuery.md5.js加密密码后后台怎么解密?
MD5不是加密算法,它是Hash算法,所以它不可逆,也没法还原成原文。
你可以用base64、异或或者aes des等加密算法去实现。
1、base64加密
在页面中引入base64.js文件,调用方法为:
?
123456789101112131415161718
!DOCTYPE HTMLhtmlheadmeta charset="utf-8"titlebase64加密/titlescript type="text/javascript" src="base64.js"/scriptscript type="text/javascript" var b = new Base64(); var str = b.encode("admin:admin"); alert("base64 encode:" + str);//解密 str = b.decode(str); alert("base64 decode:" + str);/script/headbody/body/html
2、md5加密
在页面中引用md5.js文件,调用方法为
?
1234567891011121314
!DOCTYPE HTMLhtmlheadmeta charset="utf-8"titlemd5加密/titlescript type="text/ecmascript" src="md5.js"/scriptscript type="text/javascript" var hash = hex_md5("123dafd"); alert(hash)/script/headbody/body/html
3、sha1加密
据说这是最安全的加密
页面中引入sha1.js,调用方法为
?
1234567891011121314
!DOCTYPE HTMLhtmlheadmeta charset="utf-8"titlesha1加密/titlescript type="text/ecmascript" src="sha1.js"/scriptscript type="text/javascript" var sha = hex_sha1('mima123465') alert(sha)/script/headbody/body/html
一下为js们的源代码
base64.js:

刚开始学JQuery,有jquery-1.8.0.js和jquery-1.8.0.min.js两个js文件,请问要引进哪个js?
两个功能是一样的,min的那个是压缩过的,文件比较小,因为把空格什么的都压缩掉了,所以打开看上去比较乱,如果你想研究一下里面的代码,就用没有min的那个。
jquery.sha1.js怎么调用加密
jquery.sha1.js 具体解决方案如下:
用script标签引入,,,,代码
script src="....."/script
script language="JScript" runAt="server"
function add(x, y)
{
return ((x0x7FFFFFFF) + (y0x7FFFFFFF)) ^ (x0x80000000) ^ (y0x80000000);
}
function MD5hex(i)
{
var sHex = "0123456789abcdef"
h = "";
for(j = 0; j = 3; j++)
{
h += sHex.charAt((i (j * 8 + 4)) 0x0F) +
sHex.charAt((i (j *) 0x0F);
}
return h;
}
