What happens after the Certificate in SQL Server gets expired?

Question

I have a certificate with my SQL Server Database. What will happen after the certificate gets expired?

Will the record insertion, selection, deletion will work after certificate gets expired?

Answer 1

If your certificate gets expired there will be no effect. Certificate expiration is not enforced when the certificate is used for encryption.

Answer 2

It looks like you're using Transparent Data Encryption. If the certificate that protects the database master key expires, I'm pretty sure that the database will fail to start.
