Configuring the size of public certificate resources

For certificates that are managed by IBM Cloud® Certificate Manager, you can change the private key size of public certificates that are provided by Maximo® Application Suite.

About this task

By default, certificates that are issued by Certificate Manager use a private key size of 2048 bits. You can change the default private key size for Maximo Application Suite public certificates that are issued by Certificate Manager to one of the following values:

2048
4096
8192

Changing the private key size does not apply to manual certificates.

Procedure

In the Red Hat® OpenShift® Container Platform console, from the side navigation menu, click Administration > CustomResourceDefinitions.
On the CustomResourcesDefinitions page, click Suite.
On the Instances tab, select the instance that you want to update.
On the YAML tab for the instance, in the settings section, update the size for certManager.certificates.privateKey to one of the following values:
- 2048
- 4096
- 8192
The following example shows changing the size to 8192.
```
settings: 
  certManager: 
    certificates: 
      privateKey: 
        size: 8192
```
Save your changes.
