What is the default expiry date while creating a certificate for the TDE encryption?

Do TDE certificates expire?

Do not panic, a certificate used in TDE will continue to work even after its expiration date. This is because the Database Encryption Key (DEK) in the user database is the key that encrypts the data at rest. DEK is the symmetric key stored in the user database boot record.

How long does TDE encryption take?

You can see that the encryption took about 30 seconds to complete for (just under) 1GB of data. This isn't intended to be a formal benchmark, but rather just to give you an idea of the order of magnitude of time this might take to encrypt your own databases.
