Q.  How do I convert a String into its equivalent ASCII hex characters?

A.  Here's a function that efficiently does that:

String stringToHex(final String in) {
	StringBuilder out = new StringBuilder(in.length() * 2);
	
	for (int i = 0; i < in.length(); i++) {
		out.append(Integer.toHexString(in.charAt(i)));
	}
	
	return out.toString();
}
