Anatomy of an E2EE ActivityPub Note in Enigmatick
Over the break I spent some time revamping my structs and enums for handling #E2EE #ActivityPub exchanges. This is what I have at the moment for the initial Create from the client (this is subject to change).

I've adopted the mediaType and encoding attributes from the draft ActivityPub specification. And I've standardized the Welcome message to incorporate those.
The Create includes the Welcome and a VaultItem as instruments rather than being sent as separate activities. The Welcome can include any number of recipients, so one within the activity should be sufficient.
The VaultItem is specific to the #Enigmatick client and isn't intended to be federated. That's how I'm handling ongoing access to the decrypted data; the VaultItem is a symmetrically encrypted representation of the original content that can be safely stored on the server for repeated use by the client. I'll need to eventually update the @context with that extension.

We're expanding beta testing for #Holos on Android before the public release.
Quick reminder: Holos runs a full ActivityPub server on your phone, your data stays with you.

Interested? Let us know! iOS coming next.

@silverpill @julian Fair point.
I suppose I was thinking of the ability to assign it to a shortened name in the @'context - but this is probably relatively unimportant once it's been gzipped.

>The ability to make up brand new, guaranteed-unique identifiers on the fly is probably the thing I like most about JSON-LD.
But it is not a JSON-LD thing, right?
A JSON document can have property names that are URIs, or reverse-DNS strings, or UUIDs, or longNamesThatIncludeSoftwareNameAndVersion. All of those can be globally unique.
-
@fentiger@mastodon.social the purportedly world-ending effects of property collisions are overblown, imho.

@julian The ability to make up brand new, guaranteed-unique identifiers on the fly is probably the thing I like most about JSON-LD.
As you imply, though, it's not really a problem in practice, because devs are used to JSON, and know what happens when you add extensions to standards.
