Generate unique CRC32 CID string - PhoenixInteractiveNL/emuControlCenter GitHub Wiki
Depricated but still handy to generate a unique CRC32 (ECC CID) per ECC installation on a computer, code example:
$ciString = @$_SERVER['USERDOMAIN']."|".@$_SERVER['TEMP']."|".@$_SERVER['TMP']."|".@$_SERVER['APPDATA']."|".@$_SERVER['COMPUTERNAME']."|".@$_SERVER['HOMEPATH'];
$ciCheck = sprintf('%08X', crc32($ciString));
