Cl@ve Firma

The Electronic Office of the DGOJ, amongst its electronic signature procedures, has a new cloud signing system called Cl@ve Firma.

Using Cl@ve Firma, all those submissions made via our Electronic Office can be signed, as well as the payment of fees through the DGOJ payment gateway.

Cl@ve Firma is:

Accessible: Centralised certificates, or "certificates in the cloud" allow citizens to electronically sign from any device with an internet connection and without any additional equipment.

Reliable: It is based on the use of electronic certificates issued by the Directorate-General of Police (DGP) and securely held by the DGP itself and Social Security Information Technology Management (GISS).

Secure: The signature process is carried out with the highest level of security, which means that the enhanced  Cl@ve permanente will be used, that is, one in which, in addition to entering the user and password, a single-use password must also be provided that will be received via SMS sent to the phone number associated with the certificate holder at the time of registration.


How do you use Cl@ve Firma?

To obtain a centralised certificate or 'certificate in the cloud', with which you can sign using the Cl@ve Firma system, you must follow the steps below.

1. You must be registered in the Cl@ve Permanente system.

Cl@ve permanente:  It is an authentication system designed for people needing frequent access to the Administration’s electronic services. It is based on the use of a user code, your ID number or foreigner identification number (NIE), and a password.

2. Within the electronic signature options of the DGOJ's Electronic Office, select the Cl@ve Firma system.


3. The system will report on the centralised certificates available in order to sign. If no certificate is held, the DGOJ's Electronic Office gives the user the option of generating one.
The system will redirect the user to the Cl@ve Firma platform so that the new centralised certificate can be generated.

You must complete all the forms shown to complete the process of generating the certificate.

Once the certificate is successfully generated, the system will return to the DGOJ's Electronic Office where the new certificate will be displayed and be available for immediate use.
