How to restore a deleted SSL certificate in WebSphere??
Scenario:
 I created a CSR and sent to a 3rd party CA for Signing. I received the third party certificate, and then installed the certificate. Accidentally I deleted the certificate from cell default key store, personal certificates.  I am unable to install the certificate again now. I have to restore the certificate. How Can I restore the personal certificate now?
Procedure
  1. Click Security > SSL certificate and key management.

  1. Under Related Items, click Key stores and certificates.

  1. From the Keystore usages drop-down list, select "Deleted certificates keystore".
  2. Click DmgrDefaultDeletedStore or NodeDefaultDeletedStore.
  3. Under Additional Properties, click Personal certificates.
  4. Select a certificate.
  5. Select Export
  6. Click OK.
  7. Perform the following:
    • • Enter the keystore password of the deleted keystore. (If you have not changed your password it must be using the default password.)
    • • Enter The alias to be assigned to the certificate (in the key store that will receive the certificate).
    • • Select the ‘Managed key store’ radio button.
    • • Select the key store from the drop down list that will receive the certificate.
