Frequently asked questions

You ask, we answer


Electronic signature is a legally valid means of signing and electronic identification of a legal or natural person governed by the laws of the Republic of Lithuania. Documents signed with an electronic signature bear the same legal standing as paper documents signed in the traditional (handwritten) manner.

It is widely used for signing various electronic documents (letters, contracts), connecting to electronic government gateways, banks or electronic service systems of other institutions.

The legal regulation of all electronic signatures, electronic seals and timestamps is laid down in the Regulation (EU) No 910/2014 of the European Parliament and of the Council on electronic identification and trust services for electronic transactions in the internal market (hereinafter referred to as the eIDAS Regulation).

The legal regulation of eIDAS in Lithuania is also regulated by the Law on Electronic Identification and Trust Services for Electronic Transactions, which regulates the legal effect of electronic signature, electronic seal, electronic timestamp and trust services, obligations of trust service providers and users, terms of and procedure for suspension and revocation of qualified certificates for electronic signature, electronic seal or certificates for website authentication, and supervision of trust service providers.

Qualified electronic signatures are considered to be the ultimate security tool.

Only official providers on the EU trust services list can issue a qualified electronic signature certificate. A document signed with a qualified e-signature has the same legal standing as a hand-signed document. The regulation and legislation regulating this signature is the uniform across the EU, while compliance at national level is supervised and enforced by each EU country independently.

In Elpako, documents can only be signed with a qualified electronic signature, which has the same legal effect as a handwritten paper document. It is important to note that the requirements for a qualified electronic signature are identical in all EU countries, therefore, documents signed in Elpako are legally valid not only in Lithuania, but also throughout the European Union.

Elpako’s qualified electronic signature ensures the highest data security. This electronic signature is fully compliant with the trust measures listed in the European Union’s list of trust service providers. The security of the signature is also guaranteed by a surety bond issued by an insurance company.

In Lithuania, electronic signatures are already considered an indispensable part of personal and professional comfort by natural and legal persons.

Electronic documents signed at the touch of a button create a new user experience and allow unrestricted access to all the benefits of the digital space.

It also actively contributes to the conservation of natural resources by eliminating paper documents and saving time spent travelling to exchange documents.

Document formats

Elpako works with ADOC, PDF, PDF-LT and ASiC specification documents that can be signed with a qualified electronic signature.

The most universal and popular format is PDF, which is recognised throughout the European Union.

PDF is an electronic document format in which an electronic signature can be embedded.

ADOC is an electronic container that can hold electronic documents and e-signature data in various formats. The ADOC container can hold documents in various formats, such as .docx, .xlsx, .pptx and .pdf.

PDF documents signed in Elpako can be accepted and processed throughout the EU.

ADOC is an electronic repository or container for electronically signed electronic documents. After signing, the Elpako user can download the signed document. Documents signed in Elpako (for example, a contract or an application) take the extension “.adoc”, i.e., a container containing the signed documents, the data related to the document and the e-signature.

The ADOC format is convenient in that the user can place files of different formats in this container, such as .docx, .xlsx, .pptx, .ppsx, .odp, ; .pdf” .tif., .tiff, .jpg, .jpeg, jfif, .png, .odt, and.ods.

The ADOC format is widely used in Lithuanian public sector institutions, as it meets the requirements of the Specification of Electronic Documents Signed by Electronic Signature ADOC-V1.0 approved by the Department of Archives under the Government of the Republic of Lithuania. The documents drawn up in Elpako fully meet these requirements.

Signing documents in ADOC is fast, convenient and efficient. Elpako makes it possible for users to view ADOC documents and e-signature data that can be verified in real time.

The ASiC document format is an electronic document format used in other European Union countries. This type of document, just like the ADOC, can contain multiple files that are signed. When preparing this type of document, it should be verified whether the recipient will be able to accept this type of document, as not all parties are able to read and handle these document types.

The system also features signatures for documents in PDF format, which is used in many countries. If you need to sign a large number of documents in other formats, please e-mail us at [email protected]. We will make an offer that meets your needs.
