I just released version 0.7.0 of #rsop, a stateless #OpenPGP ("SOP") CLI tool based on @rpgp:
https://crates.io/crates/rsop/
This version uses the new rPGP 0.16.0, with streaming message support.
It also comes with a number of bugfixes.
For more on #SOP, see https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/
