Why Continuous Sealing Matters
Creative work evolves. A single proof point captures one moment — but a timeline of sealed versions builds a comprehensive, tamper-evident history of your creative process.
Each seal creates an independently verified RFC 3161 timestamp from a trusted timestamp authority, tied to the exact file via SHA-384 cryptographic fingerprint. Together, they form a provenance chain that can show when a specific version of your work existed and how it developed — all without uploading your files to anyone.
Your original files never leave your device. Only cryptographic hashes are sent for timestamping.
Common Questions
Nothing. Your sealed records are permanently tied to the RFC 3161 timestamp token and the cryptographic fingerprint of your original file. They remain independently verifiable by anyone, at any time, using the Seal ID and the original file — regardless of your subscription status. Canceling ends future sealing access; it does not affect records you have already created.
No. Basic timestamp services sell a fixed number of timestamp credits — you pay per stamp and stop when the quota runs out. CREATORSEAL gives you unlimited sealing plus creator-ready infrastructure: a Receipt of Provenance Record, a raw evidence bundle with the timestamp token and supporting files, public verification by Seal ID or file fingerprint, and revision linking so you can build a verifiable version history across drafts. The goal is a complete provenance trail, not a receipt count.
Full access to everything in the Professional plan — unlimited seals, PDF receipts, raw evidence bundles, public verification, and email delivery. No credit card required to start. After 3 days, sealing requires a Professional subscription. Your existing sealed records remain valid and independently verifiable regardless.
Yes. Verification works without a CREATORSEAL account and without uploading your file anywhere. Go to creatorseal.app/verify, enter the Seal ID, and drop in the original file. The file is fingerprinted locally in your browser and compared to the recorded hash. The underlying standard — RFC 3161 — is open, so the timestamp token in your evidence bundle can also be verified independently using standard tools, without relying on this platform at all.
