Technical information on the electronic signature process

From April 2015, support for NPAPI has been disabled by default in Google Chrome.

Similarly, other companies have announced the possibility that future versions of their browsers will no longer support Java applets by default. In any case, for security reasons, it is possible that your browser is not configured to support applets.

In any event, the  Directorate-General for the Regulation of Gambling has  three solutions for signing  that can be used depending on the browser's  capabilities:

  1. Signing with Java applets
  2. Cl@veFirma
  3. Self-signing or signing without applets
  4. Signature with DNIeRemote


1. Signing with Java applets Vuelve al inicio de la página

This solution can be used if the browser has the capacity to process applets and you have a class 2 electronic certificate or electronic ID (DNI).

For more information about certificates and electronic signatures, see the  help page on electronic certificates and signatures


2. Cl@veFirma Vuelve al inicio de la página

The Electronic Office of the DGOJ,  amongst its electronic signature procedures, has a  cloud signing option 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 gambling tax revenues.
Cl@ve Firma  allows citizens to sign electronically  from any device with an internet connection  and without any additional equipment or software installation being required.

3. Self-signing or signing without applets Vuelve al inicio de la página

When a signature is required, the user's browser launches a request that is captured by the signature application distributed by MINHAC AutoFirma, which has been previously installed on the user's computer. This application is responsible for signing the document sent to you from the DGOJ’s Electronic Office and automatically connects with the DGOJ systems to return it when signed.

The solution works both for the registration of requests from the electronic office and for signing fee payment requests through the payment gateway.

Signature on Server for the electronic registration of requests

When registering a request electronically from the electronic office, the applicant is requested to electronically sign it. If it is detected that the browser does not support applets, or JavaScript support has been disabled, the option to sign is passed to the AutoFirma application.


The AutoFirma application is started, first showing a message requesting external protocol execution in order to start the application. Once the application has started, the certificate will be requested with which the signature has to be made from among those installed on the user's computer and, once signed, the signed document will be automatically sent to DGOJ's systems for processing.



Signature on the Server in payment requests for gambling tax

The signature operation on the payment gateway is identical to the one mentioned above for the electronic register. Before finalising the signature process, the applicant must digitally sign the payment request. The option of using Autofirma is given to carry out this procedure.


4. Signature with DNIeRemote Vuelve al inicio de la página

Allows using the electronic DNI if you do not have a smart card reader on your computer and mobile phone NFC reader available.

DNIeRemote converts your mobile device in a reader of DNIe 3.0 connected to the PC, allowing access services of electronic administration that require authentication with certificado digital, and make digital firmas documents through the corresponding applications.
