DC Algorithm in JavaScript (decrypt)

[Hydroper]

Thanks for answering, man.

I'm not sure, but I think the problem I couldn't read the file as well before is because I'm just calling a function with a argument of string, where I use a string with the binary content of the criminal.dat, but I don't use XMLHttpRequest or any other thing to get the file content... I just paste it.

Your code works as well! You can change the line to make the loop more faster, though.

Code:

for (var i = 123, j = 0; i < data.length; i++, j++)

to

Code:

for (var i = 123, j = 0, len = data.length; i < len; i++, j++)

(Because, in JavaScript, the for numeral loop limit is always calculated, then the data string length will be calculated everytime, also.)
