You just need to go through each two digit number and convert it first to its base value thus:

if number >= 0x30 AND <= 0x39 // 0 to 9
    number -= 0x30
else if number number >= 0x41 AND <= 0x46 // A to F
    number = number - 0x41 + 10 // 10 to 15
else if number number >= 0x61 AND <= 0x66 // a to f
    number = number - 0x61 + 10 // 10 to 15

then add it to the next 4 bit portion of your destination field.

Split the string into sets of two characters at a time.
Integer parse at base 16 the split parts.
Convert to char.

C#

package mypackage;

public class Program {

    public static void main(String[] args) {
        final String input = "323830303030346434313461343135383538346435323462343134343535333833303339333033363030303164346330303130313031313630343031303130353165303030653038316130643164303435323236";
        final StringBuilder builder = new StringBuilder();
        for(int i = 0; i < (input.length() - 1); i += 2) {
            final String part = input.substring(i, i + 2);
            final int intValue = Integer.parseInt(part, 16); // 16 for base 16 here
            final char character = (char)intValue;
            builder.append(character);
        }
        System.out.println(builder.toString());
    }
}

Hope this helps,
Fredrik
