Adobe Reader signature certificates validity

What does the expiry date "Valid to: ..." imply for a certificate? If I understood correctly, the digital ID can no longer be used for signing, but what happens after expiration date, is the signature readable, and can it be validated?
Is there any documentation on that?
Thank you in advance for any help on the topic.

Hi @Claudia27541025vwnb,

 

Self-signed digital IDs expire in five years. After the expiration date, you can use the ID to open, but not sign or encrypt, a document. In Acrobat, click the Edit menu and choose Preferences > Signatures.

 

You can check for further information from the given article:

https://helpx.adobe.com/acrobat/using/digital-ids.html

under the section: Change the password and timeout for a digital ID.

 

Hope this clarifies the description.

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.
