Azure AD B2C SSO: Prepare Details for Policy / Key Configuration

Ensure you are operating in the correct Azure AD B2C tenant area before you begin.

1. Sign in to the Azure portal.

2. Ensure you have selected the Azure AD B2C directory that contains the Microsoft Entra ID (formerly Azure AD) tenant that will be used to access Stellar Cyber. Navigate to the Directory selector using one of the following options:

   • Select the Directories + subscriptions icon in the portal toolbar.

   • Navigate to https://portal.azure.com/#settings/directory

   • Click the icon from your profile, then click Switch.

     

3. When the Portal settings | Directories + subscriptions page displays the list of directories, if there is only one directory listed, then no other step is required. If there is more than one directory, and the directory housing the tenant you are configuring for use with Stellar Cyber. is not currently active, click the Switch button on that row.

   

4. Now obtain the account identifying details that you will use throughout this configuration process. Navigate to the Microsoft Entra ID > Overview page.

5. Make note of the Tenant ID and Primary Domain and copy them to your worksheet for use in configuration later.

   

Generate two keys (one for signature and the other for encryption) in the Identity Experience Framework.

If you stop and return to any of the procedures in this configuration process, ensure that you switch to the correct directory before you continue so that you are working on the correct Azure AD B2C Tenant container.

1. Access All services from the top-left corner of the Azure portal.

   

2. Search for and select Azure AD B2C.

   

3. From the left navigation section for Policies, select Identity Experience Framework.

   • Options: Select Generate

   • Name: Enter TokenSigningKeyContainer.

   • Activation date (optional)

   • Expiration date (optional)

   • Key type: Select RSA

   • Key usage: Enable Signature

7. Click the Create button to create the signing key which will be used in the Azure AD B2C custom policies, later.The prefix B2C_1A_is automatically added to the name of your key.

8. The Policy Keys page is refreshed and displays the key you created. Click Add again to create the second key.

9. Create the Encryption Key using the following settings: 

   • Options: Select Generate

   • Name: Enter TokenEncryptionKeyContainer . The prefix B2C_1A_is added automatically to the name of your key.

   • Activation date (optional)

   • Expiration date (optional)

   • Key usage: Enable Encryption

10. Click the Create button to create the encryption key which will be used in the Azure AD B2C custom policies, later. The prefix B2C_1A_is automatically added to the name of your key.

    The Policy Keys page is refreshed and displays the key you created.

    

If you stop and return to any of the procedures in this configuration process, ensure that you switch to the correct directory before you continue so that you are working on the correct Azure AD B2C Tenant container.
