Create a new author certificate

An author certificate includes information about the author of the application.

It is used to create an author signature, which ensures the integrity of the application from the author since the publication of the application.

  1. Create new or select existing author certificate

    Select Create a new author certificate. If there is an existing author certificate, see how to manage certificate profile.

    Author Certificate

    With Advanced options menu, you can check Use an existing author certificate option to select either the Android keystore, or you can also choose already existing Samsung author certificate. Click Next.

    The same signing key helps in maintaining secure peer authentication between the Tizen Watch app and the Android mobile app.

    For more information, see Accessory SDK. In case of selecting a Samsung author certificate, you can just renew the certificate with the same information. This renewed certificate will be the same as your original RSA key so upgrading your application is guaranteed.

  2. Information of the author certificate

    Enter the author name and password. It is recommended to set a strong password. If you want to use the same password for the distributor certificate in the next step, select the check box as shown in the following figure:

    The author certificate must be secure. Therefore, it is recommended to create a backup. Click Browse to specify the backup location.

    If you lose the author certificate, you cannot upgrade your application signed with the same certificate.

    Click Next.

The next step is creating distributor certificate.

Create a new distributor certificate

  1. Create new or select existing distributor certificate

    Select Create a new distributor certificate to create a new certificate. If you select Select an existing distributor certificate, see Managing Certificate Profile.

    Click Next.

    Distributor certificate

  2. Information of the distributor certificate

    Select the Privilege level for the distributor certificate. The application must have a distributor certificate with appropriate privilege level to ensure that the implemented APIs work in the device.

    Set the Privilege and DUID



    To protect the device system and user private data, the Tizen security architecture is based on privileges and application signing of the Linux basic security model. Linux basic security model includes process isolation and mandatory access control. The users must have options to grant privileges for security-sensitive operations.

    • Public - No limitation. The privileges can be used by all Tizen application developers.
    • Partner - No limitation to request and get the distributor certificate with this level. But when the application is uploaded to the store, store re-signs the application with official partner level distributor certificate, only for the registered partner developer at Samsung.
    • If you have selected an option to apply same password to the author certificate and to the distributor certificate while entering author certificate information, the password is already saved. If you want to change the password, type the new password for the distributor certificate.

    • After the device is connected to the host PC, the DUID is automatically added to the list. If you want to add more devices, connect your device to your host PC via USB or WiFi. The previous DUIDs in the list are not deleted even if you disconnect the device. To delete the DUIDs, click the trash icon. For more information, see How to connect the device to PC via WiFi.

    • When you need to register devices that are more than 10, upload a txt file using Import a DUID list file menu. One DUID on a line and max 50 DUIDs are available.

  3. Finish creating the distributor certificate

    Click Next, to get the distributor certificate.

    Distributor certificate is complete

    Click Finish. You can find the created profile and its information.
