Keybase is a key directory that maps social media identities to encryption keys (including, but not limited to PGP keys) in a publicly auditable manner[. Additionally it offers an end-to-end encrypted chat and cloud storage system,] called Keybase Chat and the Keybase Filesystem respectively. Files placed in the public portion of the filesystem are served from a public endpoint,[as well as locally from a filesystem mounted by the Keybase client.
Keybase supports publicly connecting Twitter, GitHub, Reddit, Hacker News and Mastodon identities, including websites and domains under one's control, to encryption keys.
Keybase is a powerful tool and it would be great to see FME connect to this platform using a connector similar to the SlackConnector
