I just released a first draft version of #minipgp6
https://floss.social/@minipgp6/116500687374282691
minipgp6 is an intentionally small #OpenPGP library stack.
It implements v6 formats from https://www.rfc-editor.org/rfc/rfc9580 and #PQC composite key algorithms from https://datatracker.ietf.org/doc/draft-ietf-openpgp-pqc/
The complete library stack in this release adds up to ~5k LOC.
It interoperates with all modern OpenPGP libraries: https://codeberg.org/minipgp6/#interop-with-other-openpgp-implementations
A SOP CLI tool based on minipgp6 can be installed as
$ cargo install minipgp6-sop
Many thanks to @nlnet
