I just released version 0.3.1 of https://crates.io/crates/rsop, a stateless #OpenPGP ("sop") card tool based on #rPGP.
rsop natively supports OpenPGP card (hardware cryptography) devices
rsop is featured in the "OpenPGP interoperability test suite" at https://tests.sequoia-pgp.org/ (under "rpgpie", which is rsop's high level OpenPGP library).
Relatedly, I also released rpgpie 🦀️🔐🥧 v0.0.1 (https://crates.io/crates/rpgpie), an experimental high level OpenPGP API based on rpgp (rsop is built on top of rpgpie).
