3 days ago I released Johnnycanencrypt 0.9.0. Here is the changelog:

- Adds `setuptools-rust` as build system.
- Key.uids now contains the certification details of each user id.
- `merge_keys` in rjce now takes a force boolean argument.
- `certify_key` can sign/certify another key by both card and on disk primary key.

The first biggest change is related to build system, now we are using setuptools-rust to build. This change happened as dkg is working towards packaging the module for Debian.

The other big change is about certifying someone's key. We can use the primary key (either on disk or on Yubikey) to do the signing.

k = ks.certify_key(
    my_key,
    k,
    ["Kushal Das <kushaldas@gmail.com>", "Kushal Das <kushal@fedoraproject.org>"],
    jce.SignatureType.PositiveCertification,
    password=password,
)

In the above example I am signing two user ids of the key k using my_key with a PositiveCertification.
