Dynamic SSL Certificate Installation

If you have a backend with a self-signed certificate (or a certificate which is not signed by a CA) you need to import it to the client-truststore and restart the server. This feature enables you to upload the backend certificate through API Publisher while creating or editing your API. Follow the steps below to add a new certificate to any endpoint. Note that this feature supports only HTTP/REST and HTTP/SOAP endpoints.

This is available only as a WUM update and is effective from 27th November 2017 (2017-11-27). For more information on updating WSO2 API Manager, see Updating WSO2 Products.

Prerequisites

Ensure that you have downloaded the latest WUM update. For more details, see Updating WSO2 Products in the WSO2 Administration Guide.
If you are an existing user, follow the instructions given below.
1. Run the scripts inside the <APIM_WUM_UPDATED_PACK>/dbscripts/apimgt directory, according to your preferred database. For instructions on configuring databases, see Set up the database. Verify that the table AM_CERTIFICATE_METADATA has been created in your database.
2. Open the <APIM_HOME>/repository/conf/axis2/axis2.xml file. Add the following code under the PassThroughHTTPSSLSender parameter.
```
<transportSender name="https" class="org.apache.synapse.transport.passthru.PassThroughHttpSSLSender">
	...
      
      
      
      
      <parameter name="dynamicSSLProfilesConfig">
              <filePath>repository/resources/security/sslprofiles.xml</filePath>
              <fileReadInterval>600000</fileReadInterval>
      </parameter>
</transportSender>
```
  The default time to apply the certificate is 10 minutes. You can configure this by changing the <fileReadInterval> parameter. Note that the time is given in milliseconds.
3. If you use a different Trust Store/ Keystore configuration in the axis2.xml or carbon.xml files ,modify the KeyStore and TrustStore location in <APIM_WUM_UPDATED_PACK>/repository/resources/security/sslprofiles.xml file accordingly. The sslprofiles.xml file is configured with the existing client-truststore.jks

This feature currently supports only the the following formats for keystores and certificates.

Keystore : .jks
Certificate : .crt

If you need to use a certificate in any other format, you can convert it using a standard tool before uploading.

After configuring, the certificate will be added to the Gateway nodes which are defined under the Environments in api-manager.xml. In a clustering setup, as gateway configurations are identical, sync the <APIM_HOME>/repository/resources/security/sslprofiles.xml and <APIM_HOME>/repository/resources/security/client-truststore.jks among the gateway nodes. After the configured interval, the synapse transport will be reloaded in all the gateway nodes.

Adding a certificate

Log in to the API Publisher. Create a new API or edit an existing API.
Go to the Implement tab. Click Manage Certificates and click Add New Certificate
Enter the following information and click Upload.
Name Description
Alias Enter a name for your certificate.
Endpoint Select an endpoint from the dropdown list
Certificate Enter the location of your certificate file or click Browse to select through the UI
The uploaded certificate aliases will be displayed.
You can repeat from step 2 to add a certificate to the sandbox endpoint.

You add only one certificate per endpoint. Make sure that your certificates have not expired.

Deleting a certificate

To delete a certificate, click the icon adjacent to the certificate, as shown below.
