KeyManager API

Methods

saveData

Saves and stores data as a KeyManagerAlias inside the KeyManager.

void saveData(DOMString name, RawData rawData, optional DOMString? password, optional SuccessCallback? successCallback,
              optional ErrorCallback? errorCallback);

Since: 3.0

On success, this method will add a KeyManagerAlias into the KeyManager. The name attribute of that KeyManagerAlias will be set to be the value of the name parameter which is used in this method call. The packageId attribute of that KeyManagerAlias will automatically be set to be the package ID of the application which calls this method.

The ErrorCallback is launched with these error types:

• UnknownError - If the method cannot be completed because of an unknown error.

Parameters:

• name: Name to identify the data - this will be the name attribute of the KeyManagerAlias which this method adds, on success, into the KeyManager.
• rawData: Raw data to be stored.
• password [optional] [nullable]: Password to use for encrypting the data.
• successCallback [optional] [nullable]: Callback function that is called when data is successfully saved.
• errorCallback [optional] [nullable]: Callback function that is called when an error occurs.

Exceptions:

• WebAPIException

  • with error type TypeMismatchError, if any input parameter is not compatible with the expected type for that parameter.

Code example:

var data_name = "data1", raw_data = "my data";

function onSave()
{
  console.log("Successfully saved data");
}

tizen.keymanager.saveData(data_name, raw_data, null, onSave);

removeData

Removes data from the KeyManager.

void removeData(KeyManagerAlias dataAlias);

Since: 3.0

To remove data, an application must have permission to remove that data. By default, an application which saved data into the KeyManager has permission to remove the data. An application can also use the setPermission method to allow another application to remove its data.

If an application calls this method to remove data which it saved into the KeyManager, the dataAlias parameter does not require the packageId attribute.

Parameters:

• dataAlias: Alias of the data to remove.

Exceptions:

• WebAPIException

  • with error type NotFoundError, if the dataAlias cannot be found.

  • with error type TypeMismatchError, if any input parameter is not compatible with the expected type for that parameter.

  • with error type UnknownError, if the method cannot be completed because of an unknown error

Code example:

var data_name = "data1", raw_data = "my data";

function onSave()
{
  /* Do something. */

  /* Dictionary does not require package ID because the */
  /* application which is calling removeData() saved "data1". */
  tizen.keymanager.removeData({"name": data_name});
}

tizen.keymanager.saveData(data_name, raw_data, null, onSave);

Code example:

var aliases = tizen.keymanager.getDataAliasList();

if (aliases.length != 0)
{
  /* Assuming the application calling removeData() has permission. */
  /* to remove aliases[0] */
  var app_data = tizen.keymanager.removeData(aliases[0]);
}

getData

Gets raw data from the KeyManager.

RawData getData(KeyManagerAlias dataAlias, optional DOMString? password);

Since: 3.0

To get raw data, an application must have permission to get that raw data. By default, an application which saved raw data into the KeyManager has permission to get that raw data. An application can also use the setPermission method to allow another application to get and read its raw data.

If an application calls this method to retrieve raw data which it saved into the KeyManager, the dataAlias parameter does not require the packageId attribute.

Parameters:

• dataAlias: Alias of the data to get.
• password [optional] [nullable]: Password which was used to encrypt the data.

Return value:

RawData: Data.

Exceptions:

• WebAPIException

  • with error type NotFoundError, if the dataAlias cannot be found.

  • with error type TypeMismatchError, if any input parameter is not compatible with the expected type for that parameter.

  • with error type VerificationError, if the method cannot be completed because an incorrect password is used.

  • with error type UnknownError, if the method cannot be completed because of a database access failure or any other unknown error.

Code example:

var data_name = "data1", raw_data = "my data";

function onSave()
{
  /* Dictionary does not require package ID because the */
  /* application which is calling getData() saved "data1". */
  var app_data = tizen.keymanager.getData({"name": data_name});
  console.log("App data: " + app_data + " was retrieved");
}

tizen.keymanager.saveData(data_name, raw_data, null, onSave);

Code example:

var aliases = tizen.keymanager.getDataAliasList();

if (aliases.length != 0)
{
  /* Assuming the application calling getData() has permission to read. */
  /* aliases[0] */
  var app_data = tizen.keymanager.getData(aliases[0]);
  console.log("App data: " + app_data + " was retrieved");
}

getDataAliasList

Gets all the aliases which an application can access.

KeyManagerAlias[] getDataAliasList();

Since: 3.0

Return value:

KeyManagerAlias[]: Array of aliases.

Exceptions:

• WebAPIException

  • with error type UnknownError, if the method cannot be completed because of an unknown error.

Code example:

var aliases = tizen.keymanager.getDataAliasList();

console.log("Aliases: ");
for (var i = 0; i < aliases.length; i++)
{
  console.log("Package ID: " + aliases[i].packageId + ", Name: " + aliases[i].name);
}

setPermission

Sets permissions that another application has for accessing an application's data.

void setPermission(KeyManagerAlias dataAlias, PackageId packageId, PermissionType permissionType,
                   optional SuccessCallback? successCallback, optional ErrorCallback? errorCallback);

Since: 3.0

An application can only set permissions for data which it saved into the KeyManager. Therefore, the dataAlias parameter does not require the packageId attribute.

The ErrorCallback is launched with these error types:

• NotFoundError - If the dataAlias cannot be found.
• UnknownError - If the method cannot be completed because of an unknown error.

Parameters:

• dataAlias: Alias the data for which permission will be set.
• packageId: Package ID of the accessor application.
• permissionType: Permission to grant to the accessor application.
• successCallback [optional] [nullable]: Callback function that is called when permission is successfully set.
• errorCallback [optional] [nullable]: Callback function that is called when an error occurs.

Exceptions:

• WebAPIException

  • with error type TypeMismatchError, if any input parameter is not compatible with the expected type for that parameter.

Code example:

var data_name = "data1", raw_data = "my data";

function onPermissionSet()
{
  console.log("Successfully set permission");
}

function onSave()
{
  /* Dictionary does not require package ID because an */
  /* application can only set permission for data which it saved. */
  tizen.keymanager.setPermission({"name": data_name}, "9PdoiICQ4c", "READ_REMOVE", onPermissionSet);
}

tizen.keymanager.saveData(data_name, raw_data, null, onSave);

Code example:

var aliases = tizen.keymanager.getDataAliasList();

function onPermissionSet()
{
  console.log("Successfully set permission");
}

if (aliases.length != 0)
{
  /* Check that the application calling setPermission() saved aliases[0] into */
  /* the KeyManager. */
  if (aliases[0].packageId === tizen.package.getPackageInfo().id)
  {
    tizen.keymanager.setPermission(aliases[0], "9PdoiICQ4c", "READ_REMOVE", onPermissionSet);
  }
  else
  {
    console.log("This application did not save aliases[0] into the KeyManager");
  }
}
