Support for asymmetric operations

[wiktor-k]

Hi,

I've read the linked blogpost and the section "Replacing the ssh-agent with the Linux Kernel Key Retention Service" shows pkey class of functions for asymmetric RSA key operations (e.g. keyctl_pkey_sign).

As far as I understand these are not yet supported in this crate.

Would they be in scope of the project?

Thanks for your time! 👋

Hi @wiktor-k I don't think it's out of scope. Would be open to a PR if you're up for it.

That's great to hear! I'd definitely want to contribute that but as this requires a bit of work I wanted to ask in advance. (That said it may take me some time until I actually get to it 😅 , so if anyone is faster, it's good too 👍 ).

Thanks, and have a nice day! 👋
