Question

我正在寻找超快速和紧凑的Javascript代码或函数来对存储在数组中的文本进行加扰和解扰。

当用户使用浏览器进入“查看源”模式时，我只希望此文本无法读取。

有许多选项，例如在ASCII代码中添加固定数字或对字符串进行一些布尔计算，如移位，反转，更改为八进制，十六进制等。

我需要这个文本和数字字符串。如果扰乱的代码不复杂而不是像“，”，＃，$，＆amp;，等等那样的符号，那将是最好的。

var c = new Array();
c[0]=new Array( "Name","Home","City","Post code","Telephone","email","Web","Id","Number","xpos","ypos");
c[1]=new Array( "John","Street 123","1234","New York","555-1450123","john@demo.com","www.demo1.com","b",59,306380,565500);
c[2]=new Array( "Poul","Street 1234","2345","New York","555-7010123","poul@demo.com","www.demo2.com","i",113,308396,635477);
c[3]=new Array( "David","Street 12345","3456","New York","555-3111123","david@demo.com","www.demo3.com","i",129,377615,581358);

var Scrambler = function(n) { return ASCII(n)+1...; }
var DeScrambler = function(n) { return ASCII(n)-1...; }

$(function() {
for (var i = 0; i < c[0].length; ++i) {
    for (var j = 0; j < (c.length); ++i) {
        a[j][i] = DeScrambler(c[j][i]);
        }   
    }
});

有什么好主意吗？

Answer 1

ROT13，ROT47或其他替换密码怎么样？它实现起来很简单，速度快，并且不会增加字符串的长度。

Answer 2

如果您对文本进行加扰，则用户将能够看到正在传输的数据。如果您只想使用JS并使其通用，那么服务器是否可以将该数据作为UTF8字节发送？这也不属于加密。加密和混淆不一样。我提供了一个github文件的链接，该文件执行基本和数据类型转换。我猜你在哪里寻找这样的东西。

（所有字节到UTF8字符串操作都以无符号字节完成）（我同意@mishik minify（ing）你的代码是混淆的最佳方法之一）

Answer 3

我做了这个有效的解决方案来解决我的问题：

如果可能的话，我希望在这段代码中找到更好的东西。

1）在第33行中，我必须使用这个脏技巧""+c[i][j])将Array中的数字转换为字符串。但回过头来问题就是我的数组中的数字不再是数字了！这是非常快的，但如果你有任何更好的主意而不丢失数字定义，那么请。让我知道。 2）我使用的是2版ROT13和ROT18。我找到了ROT13单行代码版本：s.replace(/[a-zA-Z]/g,function(c){return String.fromCharCode((c<="Z"?90:122)>=(c=c.charCodeAt(0)+13)?c:c-26);});如何以简单的方式为这些ROT13添加数字和-_ @字母？ 3）正如您所看到的，我正在使用2D Array来存储我的代码。还有更好的建议吗？
