1、安装spark-md5包
2、新建文件md5WithChunk.js，封装md5加密文件的方法
3、调用计算文件md5的方法，得到md5处理后的文件
1、base64加密：在页面中引入base64.js文件，调用方法为：
2、md5加密：在页面中引用md5.js文件，调用方法为
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
base64.js： http://files.cnblogs.com/mofish/base64.js
md5.js: http://files.cnblogs.com/mofish/md5.js
sha1.js: http://files.cnblogs.com/mofish/sha1.js
我们可以知道：escape()除了 ASCII 字母、数字和特定的符号外，对传进来的字符串全部进行转义编码，因此如果想对URL编码，最好不要使用此方法。而encodeURI() 用于编码整个URI,因为URI中的合法字符都不会被编码转换。encodeURIComponent方法在编码单个URIComponent（指请求参数）应当是最常用的，它可以讲参数中的中文、特殊字符进行转义，而不会影响整个URL。
请注意 encodeURIComponent() 函数 与 encodeURI() 函数的区别之处，前者假定它的参数是 URI 的一部分（比如协议、主机名、路径或查询字符串）。因此 encodeURIComponent() 函数将转义用于分隔 URI 各个部分的标点符号。
一、encodeURI()//转义一个URI中的字符
语法：encodeURI(uri)//这个在编码不同的AJAX请求时，解决中文乱码问题经常用到。
二、decodeURI()//解码一个URI中的字符
语法：decodeURI(uri)
三、encodeURIComponent()//转义URI组件中的字符
四、decodeURIComponent()//解码一个URI组件中的字符
五、escape()//编码一个字符串
语法：escape(value)
六、unecape()//解码一个由escape()函数编码的字符串
