Get your simple, advanced or qualified signature certificate and sign documents with full legal value

Digital signature certificates

As a Qualified Trust Service Provider, we issue digital certificates that can be used for affixing any type of digital signature or for secure authentication to online services of the Public Administration.

Namirial’s signature certificates can be used for CAdES digital signatures (to sign any type of file), PAdES (for PDF files) and XAdES (for XML files), and for Qualified Electronic Seals for signing legal entities. They also allow the creation of LTV (Long Term Validation) signatures that are valid even after the expiration of the signature certificate and time stamp applied to documents. CNS-type authentication certificates can be used for secure access to PA online services.

All our certificates can be installed on physical devices (smart cards or tokens) or remain secure on our HSM servers. In addition to certificates that can be used multiple times for recurring signature processes, we also provide single-use certificates for use cases where a one-shot signature is required.

Signing documents with digital signatures

Authentication of users to PA online services

Our solution for Signature Certificates

Standard signature certificates last from 1 to 3 years and can be local or remote.

Local certificates are contained in a SIM installed on a smart card or USB token, which can also be Bluetooth. Remote certificates, on the other hand, remain secure on Namirial’s HSM (Hardware Security Module) type servers.

Standard certificates require prior identification and registration of the holder, either in person via a Namirial representative or remotely via video identification.

Single-use signature certificates can be used for advanced or qualified signature, last a maximum of 60 minutes from issuance and are valid for one use only (disposable or one-shot signature). The user identifies him/herself at the time and independently using SPID or CIE.
