TL;DR: TRUE can now secure university diplomas and transcripts with its own eIDAS qualified electronic seal, making them EDCI/Europass-compatible, recognized across all 27 EU member states, and ready for the EU Digital Identity Wallet. Through Mandated Issue, your institution stays the named issuer while TRUE applies the seal on your behalf, so you need no eSeal of your own. A qualified seal proves a diploma's origin and integrity (it came from your institution and hasn't been altered since); it does not assess the academic content. Today, TRUE offers higher-education institutions eIDAS qualified-sealed, EDCI/Europass-compatible diplomas in bulk.


Can qualified electronic seals be used on digital certificates in Europe?

Yes. An eIDAS qualified electronic seal can be applied to any digital document an organisation issues, from a university diploma to a course certificate, and Article 24a(1) of the eIDAS Regulation recognises it as a qualified seal in all 27 EU Member States. The seal proves that the document comes from the organisation named in it and has not changed since. TRUE Original seals diplomas and transcripts with its own qualified certificate, held since May 2026, and under Mandated Issue the university stays the named issuer.


Who provides an eIDAS qualified electronic seal for certificates and diplomas?

Two providers stand behind every eIDAS qualified electronic seal: a qualified trust service provider (QTSP) on an EU trusted list issues the qualified certificate for electronic seals, and the organization holding that certificate applies the seal to each certificate or diploma. For university diplomas, TRUE Original is that organization. TRUE Value Software AB seals with its own qualified certificate, held since May 2026, and under Mandated Issue the university stays the named issuer with no eSeal of its own.

The law draws the line. Article 3(27) of the eIDAS Regulation reads: "'qualified electronic seal' means an advanced electronic seal, which is created by a qualified electronic seal creation device, and that is based on a qualified certificate for electronic seal." Article 3(30) adds that the certificate is one "issued by a qualified trust service provider". Article 22(1) obliges each Member State to "establish, maintain and publish trusted lists" of the QTSPs it is responsible for, and Article 20(1) has every QTSP audited "at least every 24 months by a conformity assessment body." Europass sends issuers to the European Commission's trusted list browser to find a trust service provider in their country.

A university can hold a seal certificate itself or let another organization seal on its behalf. The European Commission's Europass guide to issuing European Digital Credentials calls the second route Mandated Issue and names a technology provider among those who can run it: "it may be a technology provider that, from within its system, technically seals credentials issued by its client, e.g. an education and training provider." TRUE Original seals university diplomas this way.


Why does a university diploma need a qualified electronic seal?

A university diploma needs a qualified electronic seal because a digital file has to prove where it came from, and that nobody changed it, to an employer or university that may sit in another country. An eIDAS qualified electronic seal gives the diploma a legal presumption of both in every EU Member State. Europass, the EU's own credential platform, builds on the seal: "The mandatory application of an eIDAS compliant electronic seal ensures that the credential origin can always be trusted."

A diploma is only worth what it can prove. For decades that proof was a signature, a watermark, and an embossed seal on heavy paper, forgeable by anyone with the right equipment.

That model is under real pressure. Document forgery has moved from back-room print shops to anyone with a laptop, and AI tools make convincing fakes faster and cheaper. Meanwhile employers, foreign universities, and authorities expect verification in seconds, digitally, across borders, not by phoning a registrar's office in another country and waiting for a reply.

Europe's answer points in one clear direction: portable, cryptographically sealed, machine-verifiable credentials a graduate can carry in a digital wallet. For registrars, IT directors, and digitalisation leads, the question is no longer whether diplomas go this way. It's how to get there without standing up a complex trust infrastructure of your own.


What is changing for university diplomas in the EU?

The EU is building a wallet for credentials. Under Article 5a(1) of the eIDAS Regulation, as amended in 2024 by Regulation (EU) 2024/1183, "each Member State shall provide at least one European Digital Identity Wallet within 24 months of the date of entry into force of the implementing acts" that the article names. The DC4EU project is already moving diplomas into that wallet in the ELM 3.2 data format.

Three EU initiatives are converging, and together they redraw what a "valid diploma" looks like.

  • EDCI (European Digital Credentials Infrastructure) is the EU's framework for digital education credentials: a common, machine-readable format so a diploma issued in Sweden can be read, trusted, and verified anywhere in Europe.
  • Europass is the EU platform where graduates store credentials in a personal "My Library" that any employer or institution can check.
  • DC4EU is the EU project transferring diplomas into the EU Digital Identity Wallet (EUDIW) using the ELM 3.2 data format, the same wallet that will hold a citizen's ID, and soon their academic record.

One technical requirement ties all of this together. To be EDCI-compliant, a diploma must be sealed with an eIDAS electronic seal. Europass accepts an advanced or a qualified seal, and TRUE uses the qualified one, the highest level. Without that seal, a credential can be a nicely designed PDF, but it isn't part of the EU's trusted, interoperable, wallet-ready ecosystem. And obtaining and operating a qualified seal is where most institutions hit a wall. (For the full background on the regulation, see how TRUE meets eIDAS standards.)


What does an eIDAS qualified electronic seal prove?

An eIDAS qualified electronic seal proves origin and integrity: the document comes from the organization named in the seal, and nothing in it has changed since sealing. The seal does not vouch for the grades inside.

This is a trust topic, so precision matters.

A qualified electronic seal is a cryptographic seal, issued under eIDAS by a Qualified Trust Service Provider (QTSP). Under Article 35(2) of eIDAS it "shall enjoy the presumption of integrity of the data and of correctness of the origin of that data to which the qualified electronic seal is linked", and under Article 24a(1) it is recognized as a qualified seal in all 27 EU member states.

A qualified seal proves two things:

  1. Origin: the document genuinely comes from the sealing organization. A sealed diploma can be trusted to have been issued by the institution named on it.
  2. Integrity: the document has not changed by so much as a single character since sealing. Any later alteration breaks the seal and is immediately detectable.

It is equally important to be clear about what the seal does not do. A qualified seal is not a review of the content. It does not assess, confirm, or vouch for whether a grade is correct, whether a course was passed, or whether a student earned what the diploma states. Sealing establishes who issued the document and that it is unaltered. The academic facts inside remain the institution's own. The seal carries your authority; it doesn't replace your academic judgment.

One distinction the market blurs constantly: "qualified" is a specific eIDAS term. It sits above an "advanced" electronic seal. Only a qualified seal carries the legal presumption of origin and integrity under eIDAS and is recognized as a qualified seal in every EU member state. (More in the FAQ below.)


What does TRUE Original offer universities?

TRUE's offering is a qualified seal, a blockchain anchor and EDCI compatibility, in bulk. TRUE Original seals each university diploma with TRUE Value Software AB's own eIDAS qualified electronic seal, anchors it on a public blockchain, and issues a whole graduating cohort in one batch.

As of May 2026, TRUE Value Software AB holds its own eIDAS Qualified Electronic Seal (QSeal) certificate. A qualified trust service provider on an EU trusted list issued it.

That means TRUE can do three things for your diplomas at once:

  • Apply an eIDAS qualified electronic seal, giving each diploma a legal presumption of origin and integrity that is recognized in all 27 EU member states, and making it EDCI-compliant and wallet-ready for Europass and the EU Digital Identity Wallet.
  • Anchor each diploma to blockchain. TRUE secures documents on several public blockchains, among them Ethereum and Polygon, creating a permanent, independently verifiable anchor anyone can check via QR code or verification portal, on a platform that has issued 900,000+ documents for 200+ organizations across 15+ countries.
  • Do it in bulk. Thousands of diplomas sealed and issued in a single batch: a graduating cohort, a back-catalogue digitisation, or an automated feed from your student system, not one at a time.

The result: a beautifully branded diploma that can open on your institution's own domain and carries both EU legal status and a permanent verification anchor.

Opened in the European Commission's own Europass viewer, a TRUE-sealed credential comes back verified. The seal names TRUE Value Software, and the viewer confirms the document has not been altered since it was issued.

How does an employer verify an eIDAS-sealed diploma?

An employer verifies an eIDAS-sealed diploma by opening it in a viewer that validates the seal, such as the European Commission's Europass viewer, which shows who sealed the credential and whether anything changed after sealing. A TRUE-sealed credential opened there comes back verified, with TRUE Value Software named as the sealer.

The check runs by itself. In the words of the Europass guide, "the seal's integrity is instantly and automatically checked every time a credential is viewed", and "the slightest change in the file data will result in a failure of the electronic seal verification check." No phone call to a registrar abroad.

The blockchain anchor is a second, separate check. Anyone can confirm it via QR code or the verification portal, with no account and without asking TRUE or the university. TRUE Verify, TRUE's free verification page, checks documents against their blockchain anchors. The anchor adds a public record. It adds no eIDAS status, which comes from the seal alone. TRUE's guide on how to check if a certificate is real covers the wider routine.


What sets TRUE apart for universities?

What sets TRUE apart is the combination in one service. TRUE Original seals diplomas with its own eIDAS qualified seal under Mandated Issue, adds a public blockchain anchor, and issues EDCI/Europass-compatible diplomas in bulk, while the university keeps the issuer role and runs no seal, token or HSM of its own.

TRUE offers higher-education institutions eIDAS qualified-sealed, EDCI/Europass-compatible diplomas in bulk, sealed under TRUE's own qualified seal so the university needs no eSeal of its own.

Here is how that compares with the alternatives institutions usually consider.

Sweden's national student-records consortium e-seals diplomas at the advanced level as PDFs: useful shared infrastructure for its member institutions, but not what the EU's wallet ecosystem expects, and not a commercial offering you can buy. International credential platforms like BCdiploma operate commercially but stop short of the qualified seal plus EDCI combination in Sweden, and have no Swedish footprint. Badge and verification platforms, Credly, Accredible, Sertifier, issue digital badges or blockchain-style verification; they're not qualified seal providers, and a badge is not a diploma.

With TRUE, institutions in Sweden have a commercial path to EU-recognized, wallet-ready diplomas today.

You don't build the trust stack. You don't run the seal. You don't wait for a sector consortium to catch up to where the EU is already going. Your institution stays the issuer; TRUE applies the qualified seal; your graduates carry diplomas that work across Europe, today.


How does Mandated Issue work for a university diploma?

Under Mandated Issue, you stay the issuer and TRUE applies the seal. TRUE Original seals each diploma with its own qualified certificate on the university's behalf, and the university remains the named issuer of record. When the awarding and sealing organizations differ, the Europass guide says, "these roles are clearly distinguished in the EDC Viewer".

You might assume that to issue EDCI-compliant diplomas your institution needs its own qualified seal. You don't, and that's the part that changes the economics.

Europass supports a model called Mandated Issue: one organization can issue and seal credentials on behalf of another. Your institution remains the clear, named issuer; TRUE applies the qualified seal under a mandate, with the mandate terms embedded directly in the credential. Anyone verifying the diploma sees your institution as the source.

The flow:

  1. You define the diplomas. Your student data, your design, your institution as issuer of record, fed in via batch upload or an automated connection to your systems.
  2. TRUE applies the eIDAS qualified seal under Mandated Issue, with the mandate terms embedded in each credential, and anchors the document to blockchain.
  3. You issue EDCI-compatible, wallet-ready diplomas that graduates can store in their Europass "My Library" and, as the EU Digital Identity Wallet rolls out, carry there too.

Why this matters in practice: running your own qualified seal means managing Hardware Security Modules (HSMs), certificates, and QSCD tokens: specialist work with real operational risk. One Swedish institution's rollout stalled when its own HSM device locked up. Mandated Issue removes that entire layer. You keep the issuer role and brand; TRUE carries the infrastructure.


Own eSeal or Mandated Issue: what is the difference for a university?

With its own eSeal, a university buys a seal certificate from a trust service provider and seals every credential itself. Under Mandated Issue, another organization seals for it. Europass accepts both routes for European Digital Credentials, and TRUE Original runs the second for university diplomas, with the university still named as issuer.

QuestionYour own eSealMandated Issue with TRUE Original
Who holds the seal certificate?The university, bought from a trust service providerTRUE Value Software AB, with its own qualified certificate since May 2026
Who is named as issuer?The universityThe university, with TRUE shown separately as the sealer
What does the university need first?Registration as a legal entity, the main prerequisite Europass names for acquiring a sealAn agreement with the sealing organization, which Europass requires for Mandated Issue
What does the university run?For the Europass EDC Issuer: the seal itself, "as a token or an installed certificate", not a remote sealing service, plus the NexU software, which Europass says runs only on Windows devicesNo HSM management, no certificate lifecycle, no QSCD tokens
Does a blockchain anchor come with it?Not as part of the sealYes, as a separate layer that does not make the seal qualified

Neither route asks the university to become a QTSP. A 2025 Open Identity Summit paper, "eIDAS 2.0: Evaluating the Issuance of Digital University Diplomas" by Awid Vaziry, Luca Vetter and Axel Küpper, drew on twelve expert interviews with QTSP executives, conformity assessment specialists and higher-education stakeholders. It found that "becoming a QTSP presents significant challenges for individual institutions, primarily due to security requirements, high operational costs, and complex conformity assessment processes."


What are the benefits of eIDAS-sealed diplomas for a university?

The benefits for your institution are legal weight and less work. An eIDAS-sealed diploma carries a presumption of origin and integrity in every EU Member State, and under Mandated Issue the university gets it without running a seal of its own.

  • Legally valid across the EU. A qualified seal gives diplomas a legal presumption of origin and integrity under eIDAS, and the seal is recognized cross-border in all 27 member states. (See the legal validity of digital certificates in the EU.)
  • EU Digital Identity Wallet-ready. Future-proofed for EUDIW and DC4EU, so graduates can store and present diplomas from their official EU wallet and Europass library.
  • EDCI/Europass compliance without your own eSeal. Via Mandated Issue, TRUE handles the entire sealing step: compliance without acquiring a qualified seal yourself.
  • No technical complexity. No HSM management, no certificate lifecycle, no QSCD tokens. The infrastructure that normally stalls projects is not your problem.
  • Two complementary trust layers. The qualified seal provides legal status: origin and integrity, recognized EU-wide. Blockchain adds an independent, permanent anchor on top. Separate mechanisms, separate jobs: the seal gives legal recognition, the blockchain lets anyone verify independently. Together, the strongest verification available, and to be clear, the blockchain anchor does not make the seal "qualified"; that status comes from eIDAS alone.
  • Built for bulk. Issue a full graduating cohort, or digitise years of past diplomas, in batches, not one at a time.
  • Anti-fraud by design. Against AI-generated forgeries, a qualified seal plus a permanent blockchain anchor makes a tampered or fabricated diploma immediately detectable. Compared with digital diplomas for education issued as ordinary files, it's the difference between looks official and is provably authentic.

This diploma offering extends the same trust foundation behind TRUE Vault to the credential that matters most to a graduate's career.


How does a university get started with eIDAS-sealed diplomas?

A university gets started with a demo of eIDAS-sealed diplomas end to end, or with a pilot for a single cohort. Both begin on TRUE's contact page.

The EU's move to wallet-based, sealed credentials is already underway. Institutions that prepare now will hand graduates a diploma that travels: recognized across Europe, verifiable in seconds, ready for the wallet that will soon hold it. You build none of the trust infrastructure: you stay the issuer; TRUE applies the seal.

Frequently asked questions

What is an eIDAS qualified electronic seal?

A cryptographic seal issued under the EU's eIDAS regulation by a Qualified Trust Service Provider (QTSP) on the EU Trusted List. It proves two things: the document's origin (it comes from the sealing organization) and its integrity (it hasn't been altered since sealing). Under eIDAS, a qualified seal enjoys a legal presumption of that origin and integrity and is recognized as a qualified seal in all 27 EU member states. It does not assess whether the content inside is correct; it establishes who issued the document and that it is unchanged.

Does our university need its own eSeal?

No. Through Mandated Issue, TRUE applies its own eIDAS qualified seal to your diplomas on your behalf, with your institution as the named issuer. You don't need to obtain or operate a qualified seal yourself, and you avoid the technical infrastructure behind it: Hardware Security Modules, certificate management, and QSCD tokens.

What is EDCI / Europass?

EDCI (European Digital Credentials Infrastructure) is the EU's framework and common data format for digital education credentials, so a diploma issued in one member state can be trusted across Europe. Europass is the EU's official platform where graduates store credentials in a personal "My Library." To be EDCI-compliant, a diploma must be sealed with an advanced or qualified eIDAS electronic seal, and TRUE provides the qualified one, the highest level.

Are TRUE diplomas valid across the EU?

Yes. Each diploma carries an eIDAS qualified electronic seal, which is recognized as a qualified seal in all 27 EU member states. Under eIDAS, that seal gives the diploma a legal presumption of origin and integrity, EU-wide.

What's the difference between a qualified and an advanced electronic seal?

Both are defined under eIDAS but sit at different trust levels. An advanced seal links the seal to the issuer and detects later changes, but doesn't require a QTSP. A qualified seal is issued via a QTSP on the EU Trusted List, meets stricter requirements, and is the only level that carries a legal presumption of origin and integrity under eIDAS, recognized in all member states. Europass accepts an advanced or a qualified seal for EDCI, and the qualified level is the stronger of the two. "Blockchain-verified" is a separate concept again, not an eIDAS seal of either level.

What is Mandated Issue?

A model supported by Europass in which one organization issues and seals credentials on behalf of another. TRUE applies its qualified seal to your diplomas under this mandate, while your institution remains the issuer of record. The mandate terms are embedded in each credential, so anyone verifying a diploma sees your institution as the source.

Can we keep our university as the issuer?

Yes, that's the whole point of the Mandated Issue model. Your institution stays the named issuer of record on every diploma; TRUE simply applies the qualified seal on your behalf under an embedded mandate. To a graduate, an employer, or any verifier, the diploma reads as issued by your university. TRUE never presents itself as the awarding body. It provides the sealing infrastructure behind your authority.

How does the EU Digital Identity Wallet affect diplomas?

The EU Digital Identity Wallet (EUDIW) is rolling out as the place where citizens hold official credentials, from ID to qualifications. The DC4EU project is already transferring diplomas into the wallet using the ELM 3.2 data format. Diplomas carrying an eIDAS qualified seal that are EDCI-compatible are ready for this shift: graduates can store and present them directly from their wallet. TRUE's sealed diplomas are built for that future today.

Is this an electronic signature or a seal?

It's a seal, and under eIDAS the distinction is precise. A qualified electronic signature is bound to a natural person (an individual). A qualified electronic seal is bound to a legal person (an organization). The signature side, where a named individual signs an agreement, is what TRUE Sign covers. Because a diploma is issued by the institution rather than by one named individual, the correct instrument is a qualified electronic seal: it carries your institution's authority as the issuing body. Both sit at the same "qualified" trust level under eIDAS and both are legally recognized across all 27 EU member states; they simply identify different kinds of issuer. If you've been searching for "qualified electronic signature" for diplomas, the seal is what you actually need, and it's exactly what TRUE applies on your behalf.

Who provides an eIDAS qualified electronic seal for diplomas?

A qualified trust service provider on an EU trusted list issues the seal certificate, and the organization that holds it applies the seal. For university diplomas, TRUE Original applies the seal with TRUE Value Software AB's own qualified certificate, held since May 2026, while the university stays the named issuer.

How does an employer check an eIDAS-sealed diploma?

The employer opens it in a viewer that validates the seal, such as the European Commission's Europass viewer, which checks the seal's integrity every time a credential is viewed. A TRUE-sealed credential opened there comes back verified and names TRUE Value Software as the sealer.

Where can I check that a seal provider is qualified?

In the EU trusted lists. Article 22(1) of eIDAS obliges every Member State to publish a trusted list of the qualified trust service providers it is responsible for, and Europass points issuers to the European Commission's trusted list browser to find one.

Can any organization get an electronic seal?

Any registered legal entity can: Europass says "any legally registered organisation, institution or company can obtain an electronic seal." A university that would rather not run one can have TRUE Original seal its diplomas under Mandated Issue.
