Security & Architecture

The web vault encrypts in the browser. We hold ciphertext and wrapped keys — not your passphrase.

AES-GCM

Files are encrypted in the browser with authenticated AES-GCM before upload. Integrity is checked on decrypt.

Passphrase-wrapped keys

Vault keys are wrapped with a key derived from your passphrase on your device. We never receive the passphrase.

Zero-knowledge vault

Server-side storage is ciphertext. We cannot open your files. Account email and operational metadata are still ours to hold.

Browser encrypts. Server stores blobs.

Your vault encrypts on your device with passphrase-wrapped keys. Independent security review is on the roadmap. Report a concern anytime at admin@verndr.com.

Client-side encryption

AES-GCM runs in the browser. Plaintext files are not uploaded.

Key wrapping

Your passphrase wraps the vault key locally. Losing the passphrase means we cannot recover the vault.

What we still hold

Account email, ciphertext blobs, and operational logs. That is not “no data even when compelled.”

Try the beta

The web vault is invitation-only Alpha. When a third-party audit exists, the report will be linked here. Until then, nothing to download.

No cash bounty tiers. If you find a security issue in the marketing site or the web vault Alpha, email details and reproduction steps.
