RocketShare is a zero-knowledge file-sharing tool that encrypts files client-side before upload, keeping even the service provider from reading the content.
What is RocketShare?
RocketShare is a web-based file-sharing service built on a zero-knowledge model. It takes any file (dropped or browsed from your device) and returns a secure share link that contains the encryption key in the URL fragment. The company behind the service is not named on the page, but the product is operated from the EU.
Key Features
- Zero-knowledge encryption — Files are encrypted before they leave your device; the encryption key never reaches RocketShare’s servers. Learn how →
- Client-side encryption — Encryption happens locally in your browser; the backend stores only encrypted blobs, metadata, and expiry information.
- Key-in-URL sharing — The decryption key is embedded in the share link’s fragment (hash), so the server never sees it and cannot decrypt files.
- EU-hosted storage — All encrypted file blobs are stored in the European Union, aligning with regional data-residency preferences.
- No credit card required — You can start sharing files without entering payment details; the service follows a freemium model.
- Expiry-controlled shares — Each share link can be set with an expiration time, after which the encrypted blob and metadata are removed.
- Simple upload workflow — Drag-and-drop or click to browse; files are protected instantly upon upload.
Who is it for?
- Privacy-conscious individuals — People who need to send sensitive files (e.g., tax documents, medical records) without trusting a third party with access to the content.
- Remote professionals — Freelancers or consultants sharing contracts, NDA agreements, or project deliverables with clients while maintaining end-to-end control.
- Small teams — Teams that want a self-serve, no-setup way to exchange confidential data without managing encryption keys or infrastructure.
What can you do with RocketShare?
- Send large files securely — Upload a file (no size limit stated on the page; check available quota in your freemium tier) and generate a zero-knowledge link to share via email, chat, or any channel.
- Share with optional expiration — Set a time limit for each link so recipients cannot access the file after the deadline — useful for time-sensitive proposals or temporary access.
- Share from cloud or local storage — The page mentions “Cloud share” and “Local share” (the latter marked “Soon”), suggesting future support for linking cloud drives or local network shares.
How does it work?
Upload a file via the browser. RocketShare encrypts it client-side using a key generated on your device. The encrypted blob is sent to the EU-based server, while the key is appended to the share link as a URL fragment. When a recipient opens the link, the JavaScript decrypts the file in their browser using that fragment. The server never sees the plaintext or the key.
Pricing
Freemium — a free tier is available and does not require a credit card to start. Details on paid tiers or storage/bandwidth limits are not disclosed on the page.
FAQ
Is RocketShare free?
Yes, you can use RocketShare without paying. No credit card is required to upload and share files. The freemium model may impose limits on file size or storage duration, though those limits are not specified on this page.
How is my data protected?
Every file is encrypted with a client-generated key before it leaves your device. The encryption key never reaches RocketShare’s servers — it is embedded only in the share link’s URL fragment. The server stores only an encrypted blob, along with metadata and an expiry timestamp.
Where are my stored files physically located?
All encrypted file blobs are stored on servers located in the European Union. This gives users a known jurisdiction for data residency.
