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:
The encryption works perfectly but the decryption doesn't ouput anything. What could be wrong?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>
