Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: SSH-tpm-agent – SSH agent for TPMs
This is a great idea. I now exclusively use SSH keys on hardware security modules of some kind. I use "Secretive", a mac app that does the same, plus a yubikey using yubikey-agent (https://github.com/FiloSottile/yubikey-agent; there are too many complicated ways to use SSH keys with a yubikey this is one of the friendliest ones). Depending on the security and frequency of which I access the service impacts whether I need presence confirmation or use secretive versus the yubikey.
I would be remiss to mention there are existing SSH TPM projects, not sure how this one differentiates. It seems to at least have the user experience pretty simple, similar to yubikey-agent (and secretive), and unlike some of the existing solutions which have quite a few extra steps:
-

Also check out https://github.com/FiloSottile/yubikey-agent which simplifies the setup quite a bit.

Yubikey ssh keys with Ansible, wants to be touched constantly
I'm using it on nixOS and macOS, via Nix Packages and Homebrew respectively. It's this - https://github.com/FiloSottile/yubikey-agent I'm realizing from this thread that it's not an official package. I'll go closer to the source with ykman. Thanks!

Is it possible to use AGE with a Ledger hardware device?
I think the Ledger Manager only interfaces with the GPG and SSH agents, neither of which age take advantage of. But age does have support for Yubikeys (see https://github.com/FiloSottile/yubikey-agent). If you can interface with the Ledger hardware device as a Yubikey, this might work. I don't have experience here, just a thought.

Cloudflare Hardware Keys (Yubico Partnership)
You can use PIV for SSH just fine.
It's not OpenSSH's weird FIDO mode, but I don't like the FIDO mode anyway because it requires storing a file on the computer.

Am I the only one who's nervous when SSH-agent forwarding?
I have the same concern. I modified Pageant (Windows agent) so that it prompts me before signing anything which helps ease my mind, I only approve when I know I'm connecting to a new server. There are also options like requiring a Yubikey too (https://github.com/FiloSottile/yubikey-agent)

How to Store an SSH Key on a Yubikey
Unless I've missed something, SSH keys stored on Yubikeys are still hampered because you aren't allowed to a touch policy of "touch never".
Imagine needing to touch the Yubikey with each "git pull" or using Ansible to operate over SSH on a dozen servers in parallel, and needing to touch the Yubikey once for each server.
The feature request I'm tracking is here: https://github.com/FiloSottile/yubikey-agent/issues/95
The proposed feature would allow setting a touch policy for the SSH key.
