age seems to be the new hot thing to encrypt data.

However, when you generate a key pair, the private key just sits as a plaintext file on your computer.

Maybe I’m too used to PGP, but this makes me a bit nervous. There doesn’t see to be a key manager that allows you to pass in a key id with which you encrypt / decrypt. It’s all done using the public key directly in the command line (for encrypting), or the plaintext private key file (to decrypt).

Am I missing something? Is there a better / easier way to manage these private key files?
