js代碼加密工具
⑴ JS解密，這是什麼加密方式，如何解密
這是dean edwards的packer
推薦你一個別人做的代碼美化工具，用js實現的，可以解壓packer打包的文檔
http://jsbeautifier.org/
另外告訴你打包的工具還有
jsmin，dojo compressor，yui compressor
⑵ javascript怎樣利用C#生成的RSA公鑰對字元串加密
js對公鑰串進行加密的寫法：
依賴：RSA.js BigInt.js 和Barrett.js

function rsalogin()
{
bodyRSA();
var result = encryptedString(key, document.getElementById("pwd").value);
//alert(result);
loginForm.action="login.do?result="+result;
loginForm.submit();
}
var key ;
function bodyRSA()
{
setMaxDigits(130);
key = new RSAKeyPair("10001","","");
}
</script>
⑶ js如何加密源代碼，頁面樣式全部用js寫，如何操作
js是不能加密源碼的，換個說法，作為一種解釋性語言，如果你加密了源碼，瀏覽器怎麼解釋你的js腳本。
不過可以用插件自動壓縮。壓縮過程中，會把一些變數用a/b/c代替，而且會移除空格和換行。這會大大增加源碼閱讀難度，但是也起不到加密的作用。
如果是electron開發，可以用asar對源碼進行打包，不過這種就屬於客戶端，不是網頁了。
⑷ 怎麼用js在客戶端實現MD5加密
使用下面的函數，例如varpwd=hex_md5("helloworld");對"helloworld"進行md5加密。var hexcase = 0;function hex_md5(a) {
if (a == "") return a;
return rstr2hex(rstr_md5(str2rstr_utf8(a)))
}
function hex_hmac_md5(a, b) {
return rstr2hex(rstr_hmac_md5(str2rstr_utf8(a), str2rstr_utf8(b)))
}
function md5_vm_test() {
return hex_md5("abc").toLowerCase() == ""
}
function rstr_md5(a) {
return binl2rstr(binl_md5(rstr2binl(a), a.length * 8))
}
function rstr_hmac_md5(c, f) {
var e = rstr2binl(c);
if (e.length > 16) {
e = binl_md5(e, c.length * 8)
}
var a = Array(16),
d = Array(16);
for (var b = 0; b < 16; b++) {
a[b] = e[b] ^ 909522486;
d[b] = e[b] ^ 1549556828
}
var g = binl_md5(a.concat(rstr2binl(f)), 512 + f.length * 8);
return binl2rstr(binl_md5(d.concat(g), 512 + 128))
}
function rstr2hex(c) {
try {
hexcase
} catch(g) {
hexcase = 0
}
var f = hexcase ? "0123456789ABCDEF": "0123456789abcdef";
var b = "";
var a;
for (var d = 0; d < c.length; d++) {
a = c.charCodeAt(d);
b += f.charAt((a >>> 4) & 15) + f.charAt(a & 15)
}
return b
}
function str2rstr_utf8(c) {
var b = "";
var d = -1;
var a, e;
while (++d < c.length) {
a = c.charCodeAt(d);
e = d + 1 < c.length ? c.charCodeAt(d + 1) : 0;
if (55296 <= a && a <= 56319 && 56320 <= e && e <= 57343) {
a = 65536 + ((a & 1023) << 10) + (e & 1023);
d++
}
if (a <= 127) {
b += String.fromCharCode(a)
} else {
if (a <= 2047) {
b += String.fromCharCode(192 | ((a >>> 6) & 31), 128 | (a & 63))

} else {

b += String.fromCharCode(240 | ((a >>> 18) & 7), 128 | ((a >>> 12) & 63), 128 | ((a >>> 6) & 63), 128 | (a & 63))

}

return b

⑸ js怎麼解密，js解密工具js怎麼查看這些代碼麻煩給解決一下
首先你的加密後的代碼有誤，無法執行，應將return(c35?String.fromCharCode(c+29):
修改為return(c<a?"":e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):
c和35之間的部分你沒復制出來
這種加密的演算法的解密方法很簡單
<html>
<body>
<divid="test"></div>
<scripttype="text/javascript">
document.getElementById('test').innerHTML=將需要破解的代碼全部復制過來，注意你原來的代碼不對，請通過替換先將上面說的那個錯誤改正
</script>
</body>
</html>
將上面的代碼保存成html文件，打開此文件即可看到加密前的內容，由於你的問題解密後是廣告語，所以不在此處給出，自己試一下
⑹ 已知一個網頁RSA加密js腳本，如何引用它對一串數字加密我不懂裡面的函數，不知該怎麼套用函數，求指教
其實過程都不用太去了解。你知道其中的幾個函數就行了。。
知道幾個參數： setMaxDigits （）這個裡面的值
//生成rsa的key
function RSAKeyPair(encryptionExponent, decryptionExponent, molus) {
//加密 字串輸出函數
function encryptedString(key, s)
----自己寫一個簡單的 函數，引用入密碼就可以了
⑺ js有沒有md5加密函數
這個不一定用md5 js沒有原生的md5方法 不過可以從網上搜一搜
⑻ 如何在前端調用js對密碼進行加密
加密和解密原則上都應該在後台完成才合乎常理，如果在前端加密，就好比在眾目睽睽之下化妝易容，然後聲稱自己是另一個人一樣，沒意義啊。
如果一定要在前端加密，可以這樣：
<input type="submit" name="submit" value="注冊" onclick="var pwd=document.getElementsByName('password')[0];pwd.value=md5(pwd.value);"/>
