Q: How deeply does 100 SQL Server Mistakes and How to Avoid Them cover certificate?

Explains certificate placement and operational handling, then demonstrates creation, backup, and use without developing cryptographic theory.

As explained in 100 SQL Server Mistakes and How to Avoid Them

A certificate is a cryptographic object containing a public key and identity information that can support encryption or authentication.

A certificate is a cryptographic object used to protect encryption keys. In SQL Server, a database master key can encrypt a certificate, which can then protect a symmetric key used to encrypt data. section 14.6.1

Mistake: treating a certificate as disposable.

Losing the certificate can make encrypted backups unrecoverable. Back it up, including its private key, to a safe location before using it. section 12.11
For column encryption, place the certificate below the database master key and above a symmetric key; store encrypted values as VARBINARY. section 14.6.1
