XCA recognizes your CA certificates if the CA flag in the Basic Constraints is set to true and if there is a corresponding private key. In this case the CA submenu in the context-menu is enabled.

For building the chains the CA flag is disregarded instead it consideres the issuer name and the signature to decide which certificate is the issuer.

7.2 Generating certificates

After clicking on the New Certificate button the Certificate Wizard will be started to ask all needed information for generating a new Certificate. See: Wizard Certificate creation can also be invoked by the context menu of the certificate list background or by the context menu of the request. In this case the Wizard is preset with the Request to be signed.

If a CA certificate is selected in the certificate list, this certificate is preselected as signer certificate on the second page of the Wizard.

7.7 Certificate renewal

Certificates can only be renewed, if the private key of the issuer's certificate is available. Renewal is done by creating a new certificate as a copy of the original one with adjusted validity dates.
