public static function csCheck(passString:String):uint { if(!passString)return 0; var count:uint = 0; if(passString.length>=6 && passString.length<=20){ count += 20; } count += !passString.match(/[a-z]/i)?0:(passString.match(/[a-z]/) && passString.match(/[A-Z]/)?20:10); count += !passString.match(/[0-9]/)?0:(passString.match(/[0-9]/g).length >= 1?20:10); count += !passString.match(/W/)?0:(passString.match(/W/g).length >= 1?25:10); count += !passString.match(/[0-9]/)||!passString.match(/[a-z]/i)?0:(!passString.match(/W/)?2:(!passString.match(/[a-z]/) || !passString.match(/[A-Z]/)?3:5)); return count; }
