Sign arbitrary data with your SSH keys

Age uses this feature of GitHub, as an example, in the documentation:

"Encrypting to a GitHub user

Combining SSH key support and -R, you can easily encrypt a file to the SSH keys listed on a GitHub profile.

$ curl https://github.com/benjojo.keys | age -R - example.jpg > example.jpg.age"

I also like distributing public keys via DNS TXT records and have written about that some here:

That's encryption (recipient key), not signing (sender key). But yeah (r)age is pretty useful for that.

Thanks! I was already wondering if this would be possible. Signing data has its uses, but I more often have to transfer sensitive data to other GitHub users and this tool seems really useful for that!
