age implementation in Dart

[v3rm0n]

We want to use age in a Flutter app (with Yubikey and x25519) so we started by implementing a Dart package called dage.
It's not ready and not fully spec compliant, but it is functional.
We are planning to add the Yubikey x25519 functionality in a separate package as a plugin to this system.
Will there be a generic spec for age plugins at one point? Would be great if we could make our plugin work with all of the implementations.

The age plugin spec is here (I need to respond to a few comments, and then we can probably get the draft merged): C2SP/C2SP#5

Is there any plugin implementation in go yet?

[v3rm0n]

Our Dart implementation is now spec compliant and can be used as a Dart library or as an executable. It supports plugins as well but not in the plugin spec compliant way. Probably at one point we will implement that as well. Repo is here if somebody is interested https://github.com/Producement/dage

There's also a plugin for this library that enables the usage of Curve25519 and RSA operations on a Yubikey https://github.com/Producement/age-yubikey-pgp
