Can you prove later what you invoiced?

SealDoc records for every document what was created and checked. The Legal Evidence Pack is one ZIP with the PDF/A-3 document, the compliance passport, the ledger with the SHA-384 hash chain, the public keys to verify every signature offline, and a manifest with the SHA-256 of every file. Two downloads of the same pack are byte-identical.
