Restores a certificate authority (CA) that is in the
DELETED state. You can restore a CA during the period that you defined in the
PermanentDeletionTimeInDays parameter of the
DeleteCertificateAuthority action. Currently, you can specify 7 to 30 days. If you did not specify a
PermanentDeletionTimeInDays value, by default you can restore the CA at any time in a 30 day period. You can check the time remaining in the restoration period of a private CA in the
DELETED state by calling the
DescribeCertificateAuthority or
ListCertificateAuthorities actions. The status of a restored CA is set to its pre-deletion status when the
RestoreCertificateAuthority action returns. To change its status to
ACTIVE, call the
UpdateCertificateAuthority action. If the private CA was in the
PENDING_CERTIFICATE state at deletion, you must use the
ImportCertificateAuthorityCertificate action to import a certificate authority into the private CA before it can be activated. You cannot restore a CA after the restoration period has ended.
