Zero-Knowledge • End-to-End Encryption

Secure file sharing that your server can’t read — but your team can.

Wisteria is a privacy-first file platform: files are encrypted before they leave your device, keys never touch our servers, and smart anomaly detection flags suspicious downloads and logins.

✔ Client-side AES-256 ✔ RSA/ECC key exchange ✔ SHA-256 integrity ✔ AI anomaly alerts

Everything you need to share, securely

Built to feel familiar, designed to be private.

E2EE

Client-side encryption

Files are sealed with AES-256 in your browser. Only recipients with your shared keys can decrypt—servers never see plaintext.

Zero-Knowledge

Private by design

We can’t access your content or keys. RSA/ECC key exchange distributes access without exposing secrets to our infrastructure.

Integrity

Tamper-evident uploads

SHA-256 hashing confirms every byte. Recipients automatically verify files before opening to prevent silent corruption.

Access

Controlled sharing

Role-based permissions, expiring links, and one-click revoke. Share confidently with clients, classmates, or your team.

Detection

AI anomaly alerts

We surface unusual behaviour—bulk downloads, odd hours, or risky locations—so you can react before data walks.

UX

Dropbox-simple

Drag-and-drop uploads, instant link sharing, previews, and comments. Powerful security without the friction.

How it works

Encrypt on your device

We generate a unique AES-256-GCM key per file and encrypt before upload.

Client-sideZero-knowledge

Share the key securely

The file key is wrapped with the recipient’s public key (RSA/ECC) and stored as ciphertext.

X25519 / RSA-OAEPPer-recipient

Verify integrity

SHA-256 hashes ensure what’s downloaded is exactly what you uploaded.

Tamper-evidentAuto-verify

Stay in control

Revoke links, set expiries, limit devices, and track access in real-time.

Expiring links1-click revoke

Smarter security

AI flags unusual logins, bulk downloads, or risky locations before data walks.

Security at the core

Encryption

AES-256-GCM for file data, per-file keys, PBKDF for passphrases, secure RNG.

Key exchange

RSA-OAEP or X25519 for fast, safe sharing. Keys never leave the client in plaintext.

Audit & logs

Readable activity trails, download counts, and sign-ins. Export for compliance.

Frequently asked questions

Can you read my files?

No. Files are encrypted in your browser with AES-256-GCM. The keys never reach our servers in plaintext.

How do share links work?

We generate an encrypted file key and wrap it with the recipient’s public key (X25519/RSA-OAEP). You can set expiry and revoke anytime.

What if I lose my passphrase?

Because of zero-knowledge design, we can’t recover it. Add recovery options (hardware key, recovery codes) in account settings.
