XSeal adds bulk document sealing for up to 20 files at once
XSeal now supports bulk document sealing: seal up to 20 files in one action and get a signed manifest proving the whole batch is unchanged, plus a certificate for every file.
XSeal has added bulk document sealing, letting anyone seal up to 20 files in a single action instead of one at a time.
Every file in a batch still gets its own real, signed certificate, exactly like sealing a single document. XSeal also builds one combined manifest covering the whole batch, signed with the same Ed25519 key used for individual seals. The manifest's combined hash is computed from every file's hash regardless of upload order, so it proves the exact set of files is unchanged as a group, not just each file on its own.
The new bulk tool lives at xseal.nl/bulk. Anyone can drag in a batch of files, contracts, exports, or evidence, and download the resulting manifest as JSON or share its public verification link. The public manifest page re-checks the signature and recomputes the combined hash on every visit, so anyone with the link can confirm the batch is authentic without creating an account.
This is aimed at teams archiving records together, such as a set of signed contracts from the same closing or a batch of exported reports, where proving the whole collection is unchanged matters as much as proving each file individually. Try bulk document sealing at xseal.nl.
