Digital signatures given with Lithuanian mobile-ID can be conveniently verified via DigiDoc4. Lithuanian mobile-ID users can also digitally sign documents via DigiDoc.
To verify Lithuanian digital signatures, nothing needs to be configured or added separately. It is sufficient to have the standard ID-software package that can be downloaded from the install ID-software page.
NOTE: The ID-software installation page will automatically offer the latest software package compatible with your operating system.
Digital signatures given in BDOC or ASiC-E format (i.e. .bdoc or .asice files) can be verified.
To verify signatures:
- First, save the signed document to your computer (such as from the email attachment).
- Double-click on the name of the signed file: this will open the DigiDoc4 Client automatically.

Show Hide The easiest way to check the validity and use limits of an electronic signature is with the help of the DigiDoc4 Client. In order to ensure better differentiation, it uses a three-colour system in addition to an explanatory text:
- green means that everything is OK
- yellow means that the user must be careful and decide on the suitability of a specific signature themselves
- red means that the signature cannot be regarded as valid in the given situation
Signature validity marking:
- Signature is valid – marked with green This digital signature is equal to a hand-written signature.
- Signature is valid (Restrictions) – marked with green and yellow. This is used if the signature level is AdES/QC, i.e. it is not a signature equal to a hand-written signature, but it may still be suitable for use in a specific situation. More information can be obtained from the signature details.
- Signature is valid (Warnings) – marked with green and yellow. The warning is usually displayed if the signature is valid, but the container has a specific characteristic. Usually containers acquire such characteristics by accident in the creation process. The warning is displayed because containers cannot be changed without the signature becoming invalid. More information can be obtained from the signature details.
- Signature is unknown – marked with red. This means that the program was not able to check the signature’s validity at the moment. More information can be obtained from the signature details.
- Signature is not valid – marked with red. This means that the digital signature has been declared invalid.

Show Hide In July 2016, a directly applicable implementing provision of the European Union came into effect, which brought into force the eIDAS Regulation. As a result, there are four levels of e-signatures:
-
Level 1 – QES (Qualified Electronic Signature)
The highest level of e-signatures, which is equal to handwritten signatures and is also called a digital signature in Estonia. The signature meets the technological requirements established in standards. The backgrounds of both the owner of the signature and the issuer of the certificate are checked. Additionally, the signature is given with a means that is deemed suitable (ID-cards, digital IDs, mobile-IDs and qualified Smart-ID accounts in Estonia. Read more about digital documents). -
Level 2 – AdES/QC – Advanced
An e-signature with a qualified certificate. The signature meets the technological requirements established in standards. The backgrounds of both the owner of the signature and the issuer of the certificate are checked. - Level 3 – AdES (Advanced Electronic Signature) – The signature meets the technological requirements established in standards, but the background of the holder of the certificate used to give the signature as well as the background of the issuer of the certificate may be unknown.
- Level 4 – Other electronic signatures – all other electronic signatures that do not meet valid standards.
-
Level 1 – QES (Qualified Electronic Signature)
