1 · Choose the file
Open Untilum and select the `.uddp` file. The application reads its public opening information without decrypting the contents.
Already have a UDDP?
Your capsule opens in three clear steps
Opening never starts with a password box. Untilum first identifies the file, checks that it is intact, and confirms whether the date is ready.
2 · Check integrity and time
Untilum reports two separate answers: whether the capsule is intact, and whether it is ready to open. If the date has arrived, you can explicitly load and verify the public time proof.
3 · Enter the password and save
Only after both checks pass does the password field appear. Choose where the opened file should be saved; Untilum shows the final name and location.
Opening checklist
What you need
- One intact UDDP copy
- The chosen date must have arrived
- The password
- A supported Untilum opener
After opening
The result stays local
The Android application saves opened files to Documents/Untilum-Opened and offers actions to open the file or show its location. Passwords and opened contents are not added to capsule history.
No hidden key
There is no password recovery
Untilum never stores the password. If it is lost, neither Untilum nor a storage provider can recover the capsule. Keep the password separately from the UDDP file and plan how the recipient will receive it.
Can I open it in the browser?
Yes. Untilum Web reads and opens the capsule inside the current browser tab. The UDDP file and password are not uploaded to the presentation server.
