Encrypt / Decrypt using ASCII?
This is a program where I have to encrypt a String to ASCII and then decrypt it back to String. I'm almost done and this is what I have so far:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<html>
<head>
<script type="text/javascript">
//This is the function that encrypts...
function thisFunction() {
var firstMessage = document.thisForm.clearText0.value;
var someString = firstMessage;
var j;
for(j = 0; j < someString.length; j++) {
var thisArray=new Array();
document.thisForm.clearText.value += thisArray[j] = someString.charCodeAt(j) + " ";
}
}
//This is the function that is supposed to decrypt...
function thisFunction2() {
var secondMessage = document.thisForm.clearText.value;
var thisArray2 = new Array(secondMessage);
for(var i = 0; i < thisArray2.length; i++) {
document.thisForm.clearText2.value += thisArray2[i] = String.fromCharCode(i);
}
}
</script>
</head>
<body>
<form name="thisForm">
Message to be encrypted...
<br/>
<textarea rows="6" cols="30" name="clearText0"></textarea>
<br/>
<input type="button" value="Encrypt" onclick="thisFunction()"/>
<br/>
<textarea rows="6" cols="30" name="clearText"></textarea>
<br/>
<input type="button" value="Decrypt" onclick="thisFunction2()"/>
<br/>
<textarea rows="6" cols="30" name="clearText2"></textarea>
</form>
</body>
</html>
The encryption works perfectly but the decryption doesn't ouput anything. What could be wrong?
