Hi Souvik,
thank you for your kind reply.
Actually I was referring to certificate-based signatures, in particular using self-signed Digital IDs. I see that the validity period is by default 5 years, and I need to understand what happens after expiration. I guess the digital ID can no longer be used for signing, but is the signature on a pdf (made when the ID was valid) still readable, and can it be validated?
Thank you in advance for your help on the matter.
