Quick decryption of js eval code
There is a piece of js code as follows:
eval(function(E,I,A,D,J,K,L,H){function C(A) The following content is omitted...
Decryption can be done by the following method:
Method 1:
Open Google Chrome, press F12, copy and paste the eval code in the Console window, press Enter to run, and then you will reach the source code.
Method 2:
Create a new html file and replace the above eval with output.
Note: The purpose of adding the xmp tag before and after is to complete the output of the html tag and does not do any escapes.
<html>
<head>
<title>evalDecryption</title>
</head>
<body>
<script type="text/javascript">
("<xmp>");
(function(E,I,A,D,J,K,L,H){function C(A)The following content is omitted。。。)
("</xmp>");
</script>
</body>
</html>
Method 3:
step:
1. Create a new html page, take the following code into it, and run it.
2. Paste the encrypted code into the text field, click Decrypt, OK!
Core code:
<script>
a=62;
function encode() {
var code = ('code').value;
code = (/[\r\n]+/g, '');
code = (/'/g, "\\'");
var tmp = (/\b(\w+)\b/g);
();
var dict = [];
var i, t = '';
for(var i=0; i<; i++) {
if(tmp[i] != t) (t = tmp[i]);
}
var len = ;
var ch;
for(i=0; i<len; i++) {
ch = num(i);
code = (new RegExp('\\b'+dict[i]+'\\b','g'), ch);
if(ch == dict[i]) dict[i] = '';
}
('code').value = "eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?(c+29):(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\\\w+'};c=1};while(c--)if(k[c])p=(new RegExp('\\\\b'+e(c)+'\\\\b','g'),k[c]);return p}("
+ "'"+code+"',"+a+","+len+",'"+ ('|')+"'.split('|'),0,{}))";
}
function num(c) {
return(c<a?'':num(parseInt(c/a)))+((c=c%a)>35?(c+29):(36));
}
function run() {
eval(('code').value);
}
function decode() {
var code = ('code').value;
code = (/^eval/, '');
('code').value = eval(code);
}
</script>
<textarea id=code cols=80 rows=20>
</textarea><br>
<input type=button onclick=encode() value=coding>
<input type=button onclick=run() value=implement>
<input type=button onclick=decode() value=decoding>
Below is the code that can be run to view the effect
