How to Timestamp Digital Content Free in Under a Minute

Timestamping digital content for free takes under a minute: open /certificar, upload your file, and the platform computes a SHA-256 hash on the server, applies a server-clock time seal, and issues a signed certificate with a public verification link. No account is required, and the free limit is 10 certificates per hour.
What sealing a file actually means
Sealing a file records two facts that anyone can later check: a unique fingerprint of your content and the moment it existed. On Veritas UGC that fingerprint is a SHA-256 hash computed server-side, and the moment is fixed first by a server-clock timestamp, then corroborated by two independent sources: an RFC 3161 time-stamp token and an OpenTimestamps proof anchored in the Bitcoin blockchain. If someone later disputes your version, the signed certificate shows that this exact file already existed on that date. The Bitcoin anchor is not instant: it starts as pending and is confirmed within hours, and from that point anyone can verify it without going through us. The RFC 3161 authority is a real time-stamping authority, though not a qualified eIDAS provider, so it corroborates the date without carrying the reinforced legal presumption a qualified stamp would.
Step by step in under a minute
First, open /certificar in any browser; you will not be asked to sign up or hand over an email address. Second, pick the file you want to protect: a photo, a video, a design, or a document. Third, confirm the upload and wait a few seconds while the server computes the hash and signs your certificate. When it finishes, you get a unique identifier, a public verification link, and a downloadable certificate to store wherever you like.
What you walk away with
The result is a compact package of technical evidence you can store or share. It includes the signed certificate with your file’s SHA-256 hash, the server time seal, and a 7-link traceability chain that documents every stage of the process. You also get a public link: anyone can visit /verify, enter the identifier or the hash, and confirm the record on their own, without asking you for anything. That open verification is what turns a simple seal into a credible argument.
A Veritas UGC seal demonstrates file integrity and date of existence, with authorship declared by the uploader; it does not verify your legal identity and does not replace official copyright registries. How much weight it carries in a dispute is always for a judge to decide, case by case. If you publish daily, register with any email, no verification step required, to keep your history in one place, or seal on the go with the native Android app before you post.
Frequently asked questions
Is sealing content on Veritas UGC really free?
Yes. The /certificar page lets you seal files without creating an account and without entering payment details, limited to 10 certificates per hour. Every seal includes a SHA-256 hash, a server-clock timestamp, a signed certificate, and a public verification link. If you want a saved history of your certificates, you can register with any email address, with no verification step.
Which file types can I seal?
The usual creator formats work: images, video, audio, text, and design documents. What matters is sealing the final original and keeping it unchanged, because the SHA-256 hash identifies that exact version. If you edit even a single bit later, the new hash will no longer match the one recorded in your certificate, and verification will flag the difference.
Does the seal have guaranteed legal value?
No, and it is worth saying plainly: the seal is technical evidence. It shows that a file with that hash existed at a given server time, with authorship declared by the uploader. It does not guarantee any court outcome and does not replace official copyright registration in your country; judges weigh each piece of evidence in context. Treat it as documentary support.
