Can someone explain the maths for me on how to work out the access masks for the api?

Otherwise im tempted to spend some time, work out all the different combinations and just hard code them into an array.

With the customisable access levels on an API key, you have an access mask which is a bitmask to tell you the access available.
For example, i have a key which enables all evemail, except notifications and has an access mask of:

50688

I just want to know if their is an easier way to find this out without first knowing.

Hey all,

Since the new Api is out I've been updating a small project I've been working on, and thought this might be handy to others. Basically it's an enum in C# (can easily be ported to others) that allows bitwise checking against certain flags.

[Flags]
public enum ApiKeyMask
{
AccountBalance = 1 << 0,
AssetList = 1 << 1,
CalendarEventAttendees = 1 << 2,
CharacterSheet = 1 << 3,
ContactList = 1 << 4,
ContactNotifications = 1 << 5,
FacWarStats = 1 << 6,
IndustryJobs = 1 << 7,
KillLog = 1 << 8,
MailBodies = 1 << 9,
MailingLists = 1 << 10,
MailMessages = 1 << 11,
MarketOrders = 1 << 12,
Medals = 1 << 13,
Notifications = 1 << 14,
NotificationTexts = 1 << 15,
Research = 1 << 16,
SkillInTraining = 1 << 17,
SkillQueue = 1 << 18,
Standings = 1 << 19,
UpcomingCalendarEvents = 1 << 20,
WalletJournal = 1 << 21,
WalletTransactions = 1 << 22,
CharacterInfoPublic = 1 << 23,
CharacterInfoPrivate = 1 << 24,
AccountStatus = 1 << 25,
Contracts = 1 << 26,
}

Enjoy :)

foreach ($this->m_callAccessGroups as $bitMask => $_) {
$remainder = ($this->m_accessmask % $bitMask);
if ($remainder!=0) { // Has this access.
$this->m_callAccess[$bitMask]['hasAccess'] = 1;
}else { $this->m_callAccess[$bitMask]['hasAccess'] = 0; }
}

Im trying to use the following to generate an array of what access the user has.


This may just be me with my programming, but could someone explain what i might be doing wrong?

(This is PHP but this forum won't let me post the tags)

$accessmask=17170696; //The accessmask to test.
$apikeytype='character'; //if the api is anything but corporation it is a character type key

$database_connection=/*Make connection to the database*/


//Fetches the contents of a table made from the apicallList.xml and stuffs it into an array.
$result=mysql_query("SELECT access_mask,Name,Description FROM apicalllist WHERE Type LIKE '{$apikeytype}'",$database_connection);

while($row=mysql_fetch_assoc($result))
{
$apicalls[$row['access_mask']]['name']=$row['Name'];
$apicalls[$row['access_mask']]['description']=$row['Description'];
}


foreach(array_keys($apicalls) as $key)
{

if(($accessmask & $key)==TRUE)
{
echo"{$apicalls[$key]['name']} => {$apicalls[$key]['description']} \n\n";
}

}

Hi, I'm not sure what language this is, but make sure you are doing a bitwise "and" with the access mask and bitmask. From the code, it looks like you are doing modulo division.

foreach ($this->m_callAccess as $bitMask => $obj) {
if (($this->m_accessMask & $bitMask)==TRUE) { // Has this access.
$this->m_callAccess[$bitMask]['hasAccess'] = 1;
}else { $this->m_callAccess[$bitMask]['hasAccess'] = 0; }
}
