Replacing an existing self-signed certificate

Occasionally, we need to replace an existing or expired self-signed certificate with a new certificate. Certificates are referenced in the runtime configuration by the SSL Configuration object and the Dynamic SSL Configuration Selection object. We can replace a certificate with a new certificate alias reference or with a new signer certificate.

The current certificate and the certificate replacement must exist in the same keystore before we can replace a certificate. Alternative Method: To replace a self-signed certificate by using wsadmin, use the replaceCertificate command of AdminTask. For more information, see PersonalCertificateCommands.

Complete the following steps in the admin console:

 

1. Click Security > SSL certificate and key management > Manage endpoint security configurations > {Inbound | Outbound} > ssl_configuration > Key stores and certificates > [keystore ].

2. Under Additional Properties, click Personal certificates.

3. Select the certificate to be replaced. The alias list must include the certificate to be replaced and the certificate to replace it with.

4. Click Replace.

5. Select a replacement certificate alias from the list.

6. We can delete one of the following types of certificates:

   • Select Delete old certificate to delete the existing or expired certificate.

   • Select Delete old signers to delete the existing signer certificates.

7. Click Apply.

 

Results

Your results depend on what you selected:

• If we selected Delete old certificate, the new certificate alias replaces all of the references to the certificate alias in the configuration.

• If we selected Delete old signers, the new signer certificate replaces all of the occurrences of the old signer certificates.

• If the new certificate alias replaces the existing alias, the WAS runtime checks to make sure that:

  • All of the SSL Configurations objects reference the certificate

  • The Dynamic SSL Configuration Selections objects and the SSL Configuration group objects reference the certificate.

• If we selected Delete old signers, the existing signer certificates are replaced.

• If we selected Delete old certificate, the existing certificate is deleted.
