You will need to have administrator permissions on your computer and you will need to close all browsers. During the installation, it is advisable to activate the automatic update of AutoFirma.

In case you need to electronically sign a document or file that you have in your computer, you can use the AutoFirma application. To do so, open AutoFirma and select the file(s) to sign. This selection can be made in two ways. The first, by clicking on the “Select files to sign” button, which will open a window from which you can select one or several documents to sign. The second way is to drag the files to be signed directly to the dark gray area with the text “Click the button or drag files or directories to this area”. The files to be signed can have any extension.

You can click on the “View File” option to preview the document to be signed and verify that it is the file you want to sign.

Once selected, click on the “Sign” button, located at the bottom of the screen, which will open a window from which you can select the digital certificate with which you wish to sign. Make sure that the chosen certificate has not expired or been revoked, as in such cases the electronic signature will be rejected. If you have installed the certificate in a different store from the operating system, you can change the store from the certificate selection screen using any of the possible options (Mozilla Firefox key store, key store in file or electronic ID).

After clicking on the “Accept” button, AutoFirma will generate a signature for each of the selected documents, in the formats established in the “Tools ➔ Preferences” menu option.

For most of the web procedures of this Ministry, the signature format is required to be XADES (excluding electronic invoices).In this page you have the necessary instructions to configure AutoSignature so that the signature format, by default, is always XADES, regardless of the format of the document to be signed (PDF, XML, ODF, etc.).

Yes, Autofirma allows you to sign documents in any format, not only PDF.

Once installed, the AutoFirma application will remain installed on your computer until you decide to uninstall it, unless you have problems with the application, in which case you can reinstall it and try again.

The certificates that AutoFirma shows by default are all those that exist in the certificate store of the operating system of the computer you are using, as long as they are valid (i.e. they are not expired or revoked). Microsoft Edge, Internet Explorer and Google Chrome browsers use the certificate store of the operating system. Mozilla Firefox has its own certificate store, which is independent of the operating system's store. In the case of using this browser, it is recommended to enable Firefox trust in the system store (only for Windows and Mac OS systems). This can be set during the installation of AutoSignature on Windows or via the option “Tools  Restore installation” on Windows or Mac OS.

On Mac OS computers, make sure that the configuration of both your electronic certificate and the “AutoSignRoot” certificate are shown with the “always trust” option (blue circle with a plus). If this is not the case, right-click on the certificate, select “Get info  Trust” and activate all available options to “always trust”.
