Recommending the following for base64 example for compatibility:

<source lang="lsl2">string keyToBase64(string s) {

  s = llDumpList2String(llParseString2List(s, ["-"], []), "");
  return
     llGetSubString(llIntegerToBase64((integer)("0x"+llGetSubString(s,0,5))<<8),0,3) +
     llGetSubString(llIntegerToBase64((integer)("0x"+llGetSubString(s,6,11))<<8),0,3) +
     llGetSubString(llIntegerToBase64((integer)("0x"+llGetSubString(s,12,17))<<8),0,3) +
     llGetSubString(llIntegerToBase64((integer)("0x"+llGetSubString(s,18,23))<<8),0,3) +

     llGetSubString(llIntegerToBase64((integer)("0x"+llGetSubString(s,30,31))<<24),0,1);

}

string integer2hex(integer in) {

  string ret = "";
  integer i;

  for (i = 0; i < 6; i++) {
     ret = llGetSubString(s, in & 0xF, in & 0xF) + ret;
     in = in >> 4;
  }
  return ret;

}

string pad_dash(string s) {
