Buy a signing certificate for 305,90 €
A document signing certificate gives a digital signature for PDF and Office files: the recipient sees a validated personal or company name, a trusted timestamp and the fact that the document has not changed since signing. The key is kept on a USB token or in the authority's cloud key store, as industry rules require. Documents are signed from Adobe Acrobat, Microsoft Office, LibreOffice and document management systems. The price starts at €305.90 a year and the catalogue holds four options: 500, 2,000 or 5,000 signatures a year, issued to a person or to a legal entity. This is an international signature on the Adobe and Microsoft roots, not a national qualified one.

What a signed document proves
Three things the recipient can verify
Who signed it
The signature carries a validated person name or company name — not just a picture of a handwritten scrawl.
That nothing changed
Any edit made after signing breaks the signature, and the viewer application says so immediately.
When it was signed
A trusted timestamp records the moment of signing, even if the certificate itself expires later.
How it works
From the order to a signed file
Identity or company check
A certificate for a person validates their identity; a certificate for an organization validates the legal entity in the register.
Issued onto a secure device
The key is stored on a USB token or in the authority's cloud storage — that is what industry rules require.
Signing
Adobe Acrobat, Microsoft Office and other applications sign the file with this certificate in a couple of clicks.
Verification by the recipient
The viewer application shows who signed the document, when, and whether it changed after signing.
How this differs from a qualified signature
An important clarification so there is no misunderstanding: this is an international signature based on the Adobe and Microsoft trust roots, not a national qualified signature such as eParaksts or an eID signature.
- It fits contracts with counterparties, reports, proposals and internal document workflow.
- It does not replace a qualified signature where the law demands exactly that — filings with government authorities, for example.

Devices, signature counts and compatibility
Yes, the signing key is kept on a secure device — an industry requirement. Cloud storage at the authority is an alternative.
It depends on the product line: 500, 2000 or 5000 signatures during the certificate term.
Adobe Acrobat and Reader, Microsoft Office, LibreOffice and most document management systems.
Both exist: Individual certificates carry a person's name, Organization certificates sign on behalf of the legal entity.
A trusted timestamp is part of the signature: it records the moment of signing and keeps the signature valid after the certificate expires.
No. This is an international signature for business documents, not a national qualified electronic signature.
From several days: the authority validates the person or the company and then issues the certificate onto the device.
No, software and drivers need separate code signing certificates — we can arrange those on request.
