Why encrypt 3GP Mobile Video files?
3GP Mobile Video files are commonly used for mobile video, older phones. When shared unencrypted, they can be intercepted, scanned, or accessed by anyone with the link — including the file sharing service itself.
FastDDL uses zero-knowledge AES-256-GCM encryption, meaning:
- Your 3gp file is encrypted before it leaves your device
- The encryption password is never stored on the server
- Even FastDDL operators cannot decrypt your file
- The encrypted file is stored on Cloudflare R2 and auto-deletes
- Tampering is detected automatically via authenticated encryption
