Is it safe to share private id_rsa key ?

I am not quite sure yet.

Depends on your trust. You actually share your private key with age utility only which uses it for decryption. They seem like good guys.

This issue is close too fast. i dont even understand yet~.

If the using private-key process is completely offline.
I guess it will be safe .

There is an instruction to do everything in docker without network connection.
