How to encrypt a Blender File file
1.Click the upload button above and select your .blend file. Files up to 500MB are supported.
2.FastDDL generates a random AES-256-GCM encryption key and encrypts your Blender File in your browser before upload. The server never sees the password.
3.You receive a shareable URL and a one-time decryption password. Send the link to your recipient through any channel.
4.The recipient enters the password on the download page to decrypt and download the Blender File file. The file auto-deletes after 48 hours.
Why encrypt Blender File files?
Blender File files are commonly used for 3D animation, modeling. 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 blend 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
