Adding a signer certificate to a keystore

Signer certificates establish the trust relationship in SSL communication. You can extract the signer part of a personal certificate from a keystore, and then you can add the signer certificate to other keystores.

Before you begin

The keystore that you want to add the signer certificate to must already exist.
Alternative Method: To add a signer certificate to a keystore by using the wsadmin tool, use the addSignerCertificate command of the AdminTask object. For more information, see the SignerCertificateCommands command group for the AdminTask object article.
Note: If the security custom property com.ibm.websphere.security.OverwriteAndReplaceOnImport is set to true then import certificate imports a certificate and overwrites an existing certificate. It then perform the certificate replace operation on that certificate. Typically, an existing certificate cannot be overwritten by a certificate that is being imported. The task also replaces all signer certificates from the original certificate and replaces them with the signer certificate from the new certificate that is being imported
