I work on an application where we encrypt the integer primary key and then use the bytes to generate something that looks like a UUID.
In our case, we don't want database IDs in an API and in URLs. When IDs are sequential, it enables things like dictionary attacks and provides estimates about how many customers we have.
Encrypting a database ID makes it very obvious when someone is trying to scan, because the UUID won't decrypt. We don't even need a database round trip.
