Highlights
Certificate or password access
Grant recipients access via X.509 certificate, a shared password, or both—fully offline, no server required.
Signed & verifiable
Every container is integrity-protected end to end; recipients can verify authenticity without trusting the channel it arrived on.
Classification labels
Attach classification, releasability, originator, and category assertions (iCLASS) directly to the container.
Works fully offline
No cloud dependency today; a federated key-access mode is planned as an addition, not a replacement.
This is an evaluation build. The installer ships with a folder of sample test certificates so you can package and open containers right away to try the format. Do not use these sample keys to protect real secrets.
Get started
Download the ZIP, extract it anywhere, and run CI_TDF.exe—no install wizard, nothing written outside the folder you extract it to. The app includes a built-in user manual and manifest reference under its Documentation tab.
