I have the following code in Java that convert Hex values to Long numbers, in the example I used the value: 'B4EEB49B04C0'
public static long HexStr2Long(String value)
{
value = value.toUpperCase();
long result = 0;
for (int i = 0; i < value.length(); i++)
{
int x = value.length() - i - 1;
char ch = value.charAt(i);
result += keys.indexOf(ch) * Pow(exponent, x);
}
return result;
}
public static long Pow(long baseNo, long x)
{
long value = 1;
while (x > 0)
{
value = value * baseNo;
x--;
}
return value;
}
public static void main(String[] args) {
long result = HexStr2Long("B4EEB49B04C0");
System.out.print("resultado: "+result+"\n");
}
The result is: 1463925582232863984
Now, I created the equivalent code in Javascript:
pow = function(baseNo, x){
var value = 1;
while(x > 0){
value = value * baseNo;
x--;
}
return value;
}
hexStr2Long = function(val){
var keys = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
var exponent = keys.length;
val = val.toUpperCase();
var result = 0;
for (var i = 0; i < val.length; i++) {
var x = val.length - i - 1;
var ch = val.charAt(i);
result += keys.indexOf(ch) * Math.pow(exponent, x);
}
return result;
}
var r = hexStr2Long(wifimac);
console.log('Result: '+r);
The result is: 1463925582232864000, this in wrong, it has to be the same as Java code.
How can I accomplish that? I've already tried to use the library (BigNumber) but without success.
