You can add a certificate to the instance from the Certificates module.

1. Navigate to System Definition > Certificates.
2. Click New.
3. Fill in the following fields (see table).

   Field	Description
   Name	Specify a unique name for the certificate.
   Expiration notification	[Optional] Select whether you want to send a notification when the certificate is about to expire.
   Active	Select whether the instance should use this certificate for secure communications and signing requests.
   Short Description	[Optional] Enter a text description of the certificate such as the requester or server name.
   Format	Select the certificate format. The instance supports the PEM and DER formats.
   Type	Select the certificate container. The instance recognizes certificates from trust stores, Java keystore, and PKCS#12 keystores.
   PEM Certificate	Enter the base-64 encoded PEM-formatted text containing the DER certificate. The instance decodes the certificate to populate the Valid from, Expires, Expires in days, Issuer, and Subject fields.

4. Click Submit.
   During the upload, the module extracts and displays the certificate's read-only properties in these fields:

   • Valid from date
   • Expiration date
   • Issuer
   • Subject of the certificate
5. Click Validate Stores/Certificates to check if the certificate is correct. If the instance encounters any errors with the certificate or keystore, it displays an error message.
