[aepmhlsj] Newest signed version

We seek a way to search "the internet" for the newest message signed by a given public key.  A simple method is for the signed message to include a timestamp as part of the signed message, and the search engine parses such timestamps.

Vaguely similar previous wanting a search engine to handle cryptographic metadata.

More complicated methods include a cryptographically secure notion of time, perhaps similar to the Bitcoin hash chain.

Motivation was downloading software from sketchy sources.
