How to import a valid copy of your electronic certificate

Windows-Import copy of the certificate in Microsoft Edge

To import an electronic certificate to the browser, you must have a valid copy of it. The icon of a valid copy will be an open envelope with a certificate peeping out and a key, and the extension .pfx or. p12. If you can't see the extension, right click on the certificate icon and go to "Properties".

In Microsoft Edge, go to the "Settings and more" menu, located at the end of the address bar, identified with the three-point icon and go to "Settings."

Click on "Privacy, search and services" in the left margin, find "Security" and click on "Manage certificates."

In the "Personal" tab, click on the "Import." Then, in the "Import Assistant," click "Next.

Click "Examine" to go to the path where the certificate copy has been saved.

Select the .pfx or. p12 file and click "Open." It is important to choose the file type "Exchange of personal information" in the drop-down menu in order to locate the copy. Click "Next" again.

If the copy was made with a password, you must indicate it and it is very important to also tick the box "Mark this password as exportable..." so that if you need to obtain a backup copy of the certificate you can export the private password. Click "Next" again.

Mark "Automatically select the certificate warehouse...." Click "Next" again and, finally, "Finish."

If the import has been correct, the message "Import is completed correctly" will appear and when the browser asks to identify itself, the certificate will appear in the selection window for authentication or signature.

Another option to import the certificate is to double click on the copy; This opens the "Import Assistant." In the first step, you must mark "Current user." This will enable the certificate to be installed in the "Personal" tab, which is the correct location of the certificate in order to correctly sign a procedure in the Tax Agency's E-Office. The rest of the options that would have to be marked or left by default would be the same.

If the copy of the certificate is not valid (the icon is a green certificate and there is no key; The file extension is .cer) is because when exporting it, the box "Exporting the private key" was not marked, which is the personal information that the certificate contains and without which it is not possible to sign. If the copy is not valid, it will be installed in the "Other persons" tab instead of in the "Personal" tab and it would not be valid to access the procedures of the Tax Agency's website.

If the certificates do not allow you to work normally, it will not be possible to make a correct copy or request renewal via the Internet. If you do not have a valid copy, you will have to request a new certificate.
