Qualified seal

A qualified electronic seal is used to mark a document to prove its origin and authenticity.

The obligation to use a qualified electronic seal has become a reality, especially for state organizations, with the end of the legislative delay in September 2018. Acquisition and operation of the on-premise sealing service is an effective way to deal with the legal requirements.

Do you need professional solutions to create qualified seals?

SEFIRA, in collaboration with the PostSignum qualified certification authority, has prepared a solution that, in accordance with the eIDAS regulation, offers a qualified seal creation device (QSealCD) held by a sealing person to create a qualified seal.

The solution is based on the OBELISK Signer product, which provides the automatic creation of qualified electronic seals and is offered in three basic variants using a smart card or HSM.
