The Security Vulnerabilities of Permanent Cloud Storage
Standard cloud storage links (like Google Drive, Dropbox, or OneDrive) frequently outlive their intended business utility. Shared links remain publicly accessible for months or years, creating security vectors for data leakage if credentials or URLs are exposed.
Ephemeral file sharing solves this problem by enforcing hard, automated physical expiration. Files exist only for the immediate window required for transfer, eliminating long-term attack surfaces.
The Ukitz Ephemeral Transfer Lifecycle
1. In-Transit Encryption: Files uploaded to Ukitz are transmitted exclusively over TLS 1.3 encrypted tunnels.
2. Isolated Sandbox Storage: Each transfer is assigned a randomly generated cryptographic job directory inaccessible to other site users.
3. 6-Digit Retrieval Token: Access is granted via a high-entropy numeric code or direct link, expiring automatically in 15 minutes.
4. Immediate Purge Capability: Senders and recipients can trigger the 'Delete Now' button at any time.
5. Scheduled Physical Cleanup: Background cleanup daemons scan storage every 5 minutes to physically erase expired directory blobs from disk.
- Verify the SHA-256 hash of highly sensitive archives using the Ukitz Hash Studio before and after transmission to confirm integrity.
- Always share the 6-digit retrieval code over a separate, secure communication channel from the link.
Step-by-Step: Sending and Receiving Files
1. Open Ukitz Share / Receive File (`/transfer`).
2. Drag and drop your file into the uploader.
3. Copy the generated 6-digit transfer code or direct download link.
4. The recipient opens Ukitz Transfer, inputs the code, and downloads the file before the 15-minute expiration timer concludes.

Frequently Asked Questions
Can an expired file be recovered by Ukitz administrators?
No. Once the scheduled cleanup cron executes, file blobs are physically unlinked from the server disk and unrecoverable.
Is there a limit on transfer file size?
The current web interface supports files up to 25 MB per transfer, optimized for fast and reliable browser-to-browser exchange.
