A couple of days ago I released Johnnycanencrypt v0.11.0. It is a Python module for OpenPGP written in Rust.

The most interesting update is for Linux users, now we have pre-built wheels for Python 3.8, 3.9, 3.10 & 3.11. You can just install that via python3 -m pip install johnnycanencrypt. You can also do the same on Intel Macs (for Python 3.10 and 3.11). But, I failed to build for Apple Silicon systems. I will work on it in the coming weeks.

To know the Yubikey card version we can call get_card_version function written in Rust.

>>> rjce.get_card_version()
(4, 3, 1)

Or directly use the function get_card_touch_policies to get a list of policies for the current Yubikey.

>>> import johnnycanencrypt as jce
>>> jce.get_card_touch_policies()
[TouchMode.On, TouchMode.Off, TouchMode.Fixed]

Then we now can also set the touch policies for a given Yubikey. For example:

rjce.set_keyslot_touch_policy(
    b"12345678", rjce.KeySlot.Authentication, rjce.TouchMode.On
)

It will be nice to see what people will build on top this. I also missed to blog about the v0.10.0 release. You should that changelog too.
