The Revenue Agency announced which has adapted the safety standards of Entratel certificates.
Given that the new standards will take effect from 30 April 2022, by that date it is appropriate to check whether, regardless of the expiration date, it is necessary to renew the certificate.
The Agency illustrates the procedure to be followed whether the telematic Desktop is used, whether you are using the Certificate Generation app.
For example, using Telematic Desktop if, once the certificates have been uploaded, the screen appears
the certificate is not to be renewed as it is already updated, as confirmed by the wording “Public Key: Sun RSA public key, 4096 bits”.
I know, the other way around, other indications appeared, like the one shown below, the certificate must be renewed
Please remember that, to renew certificates, you must first revoke them and then generate them again, with Telematic Desktop (Security menu -> Set environment) or with the Certificate Generation app (Generate environment menu -> Set environment).
