Verification links expire, registrars close and registers change. Seal the proof of your degree while the source still answers. Certify your diploma ↓

Done for you, delivered in 24 hours

Your diploma is a link now. Links die.

A scan in your cloud drive proves nothing about when it was made or whether it was edited. In 2026 ProofSnap seals your diploma, transcript and the official screen that verifies them into one certified package, delivered in 24 hours, and checkable by anyone, offline, without having to trust us.

Written by Radim Motycka, founder and lead engineer of ProofSnap, who builds the hashing, signing and timestamping pipeline described on this page.

How do you prove your degree is real, years after graduation?

ProofSnap seals your diploma, transcript and the official screen that verifies them into one certified package, delivered within 24 hours for $59.99. Every file is hashed, signed, timestamped by a qualified trust service provider and anchored in Bitcoin, so anyone can check it offline, long after the original link stops working.

Four ways the proof of a degree quietly disappears

None of these touch your degree itself. They take away your ability to show it on demand.

The share link expires

European Digital Credentials let the holder set an expiry date on the share link, and the issuer's seal behind it has its own validity period. One large university tells graduates plainly that the invitation link to their electronic diploma expires after 14 days.

The issuer disappears

Universities close and merge. Records move to a custodian or a state agency, and alumni are told to write to an office they have never heard of. Some reach it. Some do not.

The register entry changes

Public education registers record statuses such as invalid, cancelled or issued in error, and entries are corrected without notice. What the register showed last year is not recoverable next year.

There is no register at all

For many countries and for older qualifications there is no online record to point at. When paper is lost, recognition turns into an interview about what you remember.

How the certification runs

You send documents. We do the rest and deliver a finished package. Nothing about it requires you to understand hashing or timestamps.

1

Pay and upload

Pay the one-time fee of $59.99. Right after payment you land on a secure upload page, so your diploma and transcript never travel by email.

2

Tell us what verifies it

If your credential has an online verification page, a register record or a share link, send us the link and whatever is needed to open it. If it has none, we seal the documents alone.

3

We capture and seal

We capture the official screen exactly as it renders, hash every file with SHA-256, sign the manifest, add a qualified eIDAS timestamp and anchor the whole thing in the Bitcoin blockchain.

4

You get the package

Within 24 hours you receive one signed ZIP with your documents in a files/ folder and the twelve sealing files beside it, plus an email delivery note. Anyone you send it to can verify it in the free Trust Verifier or offline with the included scripts.

Identifiers you send us for a register lookup are used once, for your package, and deleted after delivery, as set out in our privacy policy. We do not publish your documents and we do not keep a searchable copy of them.

What is inside the package

One ZIP. Twelve files do the sealing, and every document you send sits in a files/ folder of its own. Structured files for machines, a readable PDF for people.

The package carries both timestamps. Everything you send sits in files/, under its own name, so a package with more documents simply contains more files.

The capture of the official screen travels as its own sealed package inside the ZIP, with its own manifest and chain of custody. Two independent layers, no clashing file names, and each layer can be checked on its own.

Your own documents preserved unchanged, so an expert can re-derive every hash from the originals

A screenshot and the underlying HTML of the verification screen, with DNS, TLS and HTTP headers captured at the same moment

A manifest listing the SHA-256 of every file, signed with a per-package RSA key

A qualified eIDAS timestamp bound to that manifest, plus long term validation data

A Bitcoin OpenTimestamps anchor, independent of us and of the timestamp authority

A chain of custody document recording each step in order

Example output. Whoever receives your package runs these checks themselves, with no ProofSnap account and no payment.

The point is not the ZIP. The point is that the person on the other side can prove it to themselves.

What the package proves

Four things the package proves, each of them checkable by the person you send it to.

That the files in the package existed in exactly that form no later than the timestamp

That nothing inside has been altered since it was sealed, down to a single byte

That the official verification screen showed those exact contents on that date, from that domain

That the record can be checked by anyone, offline, without ProofSnap existing

What proof of a degree costs in 2026

Everyone in this market sells you a step in somebody else's process. ProofSnap sells you the record you keep.

Route Published price What it gives you
Credential evaluation, WES and similar from $118 plus delivery Tells a third party what your degree is equivalent to. The report serves that process, not you.
UK ENIC Statement of Comparability £69.60 A UK comparability statement, about 15 working days once all documents and payment are received.
Primary source verification for Gulf licensing priced per package and per document The regulator receives a verification report. Required, slow, tied to one authority. The fee appears in the portal once the package is chosen.
One-off degree lookup, US clearinghouse route priced per check, paid by the employer A single confirmation, for whoever pays for it, on the day they pay.
Apostille or notarised copy of a diploma state fee plus a service fee, per document Paper legalisation for cross-border use, usually posted.
ProofSnap certified package $59.99 A sealed copy of your own documents and the official screen, verifiable offline by anyone, and yours to keep.

Prices are the providers' published figures, checked in September 2026. Each route answers a different question. This one answers the question about your own documents: what you hold, unchanged, proved as of a date you can point to.

Questions people ask before ordering

The extension

Would you rather do it yourself?

Everything on this page can be done by hand in the ProofSnap extension: certify your own files, capture the verification screen on your own machine, add a qualified timestamp when the recipient needs one.

The ProofSnap side panel with the File Certifier open

The side panel holds the File Certifier, the evidence language and the qualified timestamp toggle.

File Certification in the extension

Drop your diploma, transcript and any completion letters into the panel and seal them in one package: SHA-256 for every file, a signed manifest, a chain of custody document and a report PDF. One by one, or all of them in a single combined package.

How File Certification works

Add an eIDAS SnapPack

A qualified electronic timestamp bound to your sealed package, issued by Disig a.s., whose timestamping service is listed as qualified on the EU Trusted List. Under Article 41(2) of the eIDAS Regulation it enjoys, in proceedings in the European Union and the EEA, the presumption of the accuracy of the date and time it indicates and of the integrity of the data it is bound to.
