Simple answer: no, don’t do it. For the uses cases use something else instead of adding complexity to twtxt

@darch@twtxt.net Also you have to be very clear here about one thing.

• Twtxt is a text/plain fiel format / specification for how to minimally publish “Status Updates”. That’s really about it.
  

So if we agree on this, then “client” are a completely separate thing entirely. Many of the extensions we’ve form consensus around, documented and published – Are in fact based on conventions used by folks in the wild both in the past and present.

Encryption is no different. It’s yet another extension…

But this time with a bit of a modern twist. Using modern crypto like Saltpack which is very similar to GPG in nature, but much better/easier to work with and just as secure, privacy and robust.
