[messaging] alternative to OpenPGP?

[Mansour Moufid]

Hi everyone,

Is there an alternative to the OpenPGP message format?

There are three problems with OpenPGP, that I understand: metadata; [1]
format oracles; [2] and difficulty of implementation. [3]

There are many more problems[4] but I care about these three.

So I'm looking for an alternative message format which: has minimal
metadata; requires authenticated encryption; and is trivial to parse
with Hammer.

Does one exist?

Yours,
Mansour
