Messaging built around your files
Most encrypted messengers are good at chat and bad at files. DRIVUNO is built around your vault, so attachments and threads share the same encryption model.
Messaging
End-to-end encrypted messaging, where your files already live.
Talk to other DRIVUNO users with full client-side encryption — and attach files from your vault without ever exposing them.
“A private mailbox designed for the conversations that matter.”
For anyone who exchanges confidential messages with collaborators, clients, family or counsel.
Built for confidentiality
Sealed envelopes
Messages are sealed for the recipient's public key; the server relays opaque blobs.
Attachment-aware
Attach files from your encrypted vault; access is keyed to the recipient.
Minimised metadata
Only what is needed for delivery — and for the time needed to deliver.
Identity-pinned
Recipients are identified by cryptographic keys, not just an email address.
Frequently asked questions
Can DRIVUNO read my files?
+
No. Files are encrypted on your device before upload using XChaCha20-Poly1305. DRIVUNO servers only ever store ciphertext. The keys required to decrypt your files are derived from your password on your device and never leave it unencrypted.
What is zero-knowledge encryption?
+
Zero-knowledge is an architecture in which the service provider has no technical ability to access user data. With DRIVUNO, your master key is derived locally from your password using Argon2id. The server never sees that key, so it cannot decrypt your files even if compelled to.
Is DRIVUNO safer than Google Drive or Dropbox?
+
DRIVUNO uses a different architecture. Google Drive, Dropbox and similar consumer clouds hold the encryption keys to your files, which means their staff, automated systems, and any party with legal access can in principle read your content. DRIVUNO is designed so that this is technically not possible on our side.
What happens if I lose my password?
+
Because we cannot read your data, we also cannot reset it for you. You can configure a recovery key when creating your account. We strongly recommend storing it offline. Without your password or recovery key, encrypted data cannot be recovered — by design.
