Secure File Transfer

Secure file transfer should mean more than “HTTPS to a random upload form.” If the service stores your file, you inherit that provider’s retention, staff access, and breach surface.

BoltShare approaches secure transfer differently: encrypted WebRTC between peers and no server-side file storage of your payload.

How secure transfers work on BoltShare

Create a private share session Only people with your generated link join the transfer.

Connect peers over WebRTC Browsers negotiate a direct data channel with encryption provided by the WebRTC stack.

Stream bytes without parking them on BoltShare When finished, there is no lingering cloud object on our side to leak later.

Security properties that matter day to day

Encryption in transit WebRTC data channels are designed for encrypted peer communication.
Minimal third-party retention We do not keep your files on BoltShare storage after—or as—a hosted download.
Link knowledge required Receivers need the unique link you shared; it is not a public browseable folder.

When secure transfer is non-negotiable

Personal documents IDs, tax packs, and medical PDFs you prefer not to leave in a public transfer locker.
Source code & keys (with care) Still follow your org policies—BoltShare reduces cloud residual copies during a live send.
Journalist & researcher handoffs Move materials with fewer long-lived hosted copies.

Frequently Asked Questions

Is BoltShare end-to-end encrypted?

Transfers use WebRTC encrypted data channels between browsers. Signaling helps peers discover each other; file contents are not stored on BoltShare servers.

Can BoltShare staff download my files later?

There is no file archive on our servers to download. We never store the transferred payload as a cloud object.

What should I still be careful about?

Protect the share link like any secret URL, confirm you are sending to the right person, and keep devices free of malware. Encryption does not fix sharing with the wrong recipient.
