Here's how to digitally sign a file using a Remote Signature
In the event of a PDF or XML file, once the user clicks on "sign", a window will appear asking them to specify the desired format to sign the document.
-
Press Yes to apply a PAdES (or XAdes) signature, maintaining the .pdf or .xml format
(for further information see PAdES signature and XAdES signature) -
Press No to apply a CAdES signature, in .p7m format.
Select a destination folder for the signed file, then click on OK.
Proceed with the signing operation by pressing Yes.
N.B. We highly recommend creating a dedicated folder to store the digitally signed files.
ENTERING REMOTE SIGNATURE PARAMETERS
When launching the FirmaCerta software for the first time, the username must be configured in order to use remote signatures.
Go to Settings and enter the username provided when the certificate was issued.
N.B. Recover remote signature credentials.
Users who have lost their credentials will be asked to access their reserved area at the following address: https://portal.namirialtsp.com. Click on “I forgot my User name" and follow the instructions provided.
