Electronic Signature Certum
Electronic Signature Certum

Certum Electronic Seal in the Cloud

The Certum solution uses a Qualified Electronic Seal certificate, ensuring that every sealed document retains its full legal validity and evidentiary power.

The first electronic seal in Poland that works:

  • without a physical card or reader,
  • on mobile devices with Android or iOS,
  • on desktop computers with Windows PC or Mac OS X.

Validity period: 1 or 2 years.

This solution uses a Qualified Electronic Seal certificate which – unlike an electronic signature – does not contain the data of a natural person but only the data of a legal entity (e.g. a company, organisation, or public administration body). The service is fully compliant with the European eIDAS Regulation, ensuring that documents sealed with a Qualified Electronic Seal retain their full legal validity and evidentiary power.

Important:

  • The service is not intended for M2M applications or for mass signing of e-documents.

Usage limits:

  • The service includes 5,000 qualified timestamps per month provided by Certum.
