<p style='margin-top:0;margin-bottom:10px;'>There's some minimal support in the DataSealer class for key versioning but it wasn't really thought out and currently assumes a hardwired default key name.</p>
<p style='margin-top:0;margin-bottom:10px;'>To make rolling keys practical, particularly on a daily schedule, we need an automated way to recognize key updates.</p>
<p style='margin-top:0;margin-bottom:10px;'>We should also pull the key management out as a strategy interface so that the DataSealer is independent of the way we version keys. It can pull the default key from the interface when encrypting, and pull the named key used when decrypting.</p>
<p style='margin-top:0;margin-bottom:10px;'>Java 8 adds extensible attributes to key store entries that we might be able to use later to track key versions, but for now, we can maintain a separate file containing the current key version. This can be a number, but really is just a label to append to a base name to compute the entry alias.</p>
<p style='margin-top:0;margin-bottom:10px;'>If we poll the file in a background thread, we can spot key updates and load the new default key inside a lock so it will be rolled automatically.</p>
<p style='margin-top:0;margin-bottom:10px;'>The actual key management can be externalized into something that just maintains the keystore entries and updates the version file. Using a number is the easiest way to embed some kind of basic policy around key updates; a script can purge old keys based on their serial number, etc. But the IdP code can be oblivious to that.</p>
