Following the software update of GoSign, widely used at the university for verifying digitally signed files (particularly for files in CADES format with the .p7m extension), online registration has become mandatory.
Without registration, the software allows only 5 verifications per month. When starting the verification, if not logged in, a message appears prompting for registration.
Those who prefer not to register can use the software ArubaSign, available for both Windows and Mac, downloadable at the following address: https://www.pec.it/gestione-supporto-firma-digitale.aspx
It is recommended to not use unofficial sites for online verification of digital signatures, to avoid uploading documents to unverified services.
If necessary, you can use the online verification service of the National Council of Notaries: https://ca.notariato.it/ca
