• Added support to create exportable Key Encryption Keys (KEK) to enable key recovery in Disaster Recovery scenarios (JIRA: FSE-777).

• For existing FSE-Linux users (with FSE Agent <1.0.29)

  • Install the latest Filesystem Encryption for Linux and update the FSE policy using the policy update command to automatically change the custom metadata and enable the FILE DECRYPTION POLICY tab in the Fortanix DSM UI.
