Creating Certificates

All applications must be signed with valid certificates before they can be installed or run. This topic describes how to create a certificate profile you can use to sign your applications.

According to the Tizen policy, all applications must be signed with valid certificates before they can be installed or run. The signature verifies the source of the application and makes sure it has not been tampered with since its publication. A certificate profile is a combination of the certificates used for signing, and it can be created using the Certificate Manager. The active certificate profile is used when packaging your application.

Prerequisites

To create or import certificates, you need:

• Samsung Certificate Extension
  
  For more information, see Installing Samsung TV SDK.
• Samsung Developer account
• Device ID (DUID) for the target device on which you want to install your application

Creating a Certificate Profile

A certificate profile consists of an author certificate and 1 or more distributor certificates.

To create a certificate profile:

1. In the Tizen Studio menu, select "Tools > Certificate Manager".
   
   
   
   Note :

   In Tizen Studio 2.0 and lower, if the Tizen Studio and the Certificate Manager are running at the same time, the Certificate Manager can freeze. To avoid this issue, after launching the Certificate Manager, close the Tizen Studio.

2. Click "Cancel" on "Migration for Certificate Profile" dialog.
   
   

3. Click "+".
   
   
   
   The certificate profile creation wizard opens.

4. Click "Samsung".
   
   

5. Select "TV", and click "Next".
   
   

6. Enter a name for the certificate profile, and click "Next".
   
   

7. Add an author certificate.
   
   You can create a new author certificate or import an existing one:

   • To create a new author certificate:

     1. Select "Create a new author certificate" and click "Next".
        
        
     2. Enter the required information, and click "Next".
        
        
     3. Sign in with your Samsung Developer account.
        
        
     4. Define a backup path for your certificate file, and click "Next".
        
        
     Important

     Keep your certificates backed up in a safe location. When you update your published applications, the update must be signed with the same author certificate as the original application. If the applications are signed with different author certificates, the update can be recognized as a different application and not an update.

- If you already have an author certificate ("author.p12" file), you can import it.
To import an existing author certificate: 1. Select "Select an existing author certificate", and click "Next".
 2. Define the existing certificate, and click "Next".

8. Add a distributor certificate:
   1. Select "Create a new distributor certificate" and click "Next".
      
      
   2. Define the privilege level you need, and add the device ID (DUID) for the target device. You can enter the DUID manually, or by clicking "+" next to the connected device in the list.
      
      
   Note :

   To view the device ID, on your TV, go to "Menu > Support > Contact Samsung > Unique Device ID".

9. To close the certificate profile creation wizard, click "Finish".
   
   

To allow installing your applications on the device, launch the Tizen Studio Device Manager, right-click a folder in the connected device file system, and select "Permit to install applications".
