SpotPass downloads/checks for updates every 24 hours? This is basically identical to the system used before for manual system updates: when it's time to check for updates, SpotPass will simultaneously send a system update SOAP request to the server, and also request from nppl*.(nppl* is likely unrelated)

When there's an update available, SpotPass will then download the tmd/ticket over HTTPS and content over HTTP.(like usual)

All SpotPass content uses this container to encrypt the payload.(and possibly sign it) The cleartext payload is stored in [[extdata]].

Data following the header is encrypted, the CTR used is likely based on metadata in the header.(like the timestamp)
It appears that this file format is big-endian, unlike [[CXI]].
