Initial checks

Start by checking that there aren't any previous ssh keys inside the FIDO2 authenticator of your YubiKey. You can check if they exist by running the command below:

nix shell nixpkgs#yubikey-manager -c ykman fido credentials list

If the command above outputs a string mentioning "ssh" or "openssh", then you have already got a key generated and store on your YubiKey.

Evaluating additional authentication factors

Before generating a new ssh key to store on your YubiKey you must consider which additional required authentication factors you want to use. Below you can see a table with the available factors and their corresponding command:

(ns clj-gunzip.core
  (:require [clojure.java.io :as io])
  (:require [clojure.string :as str])
  (:import java.util.zip.GZIPInputStream
           java.util.zip.GZIPOutputStream))

(defn gunzip
  "Writes the contents of input to output, decompressed.

  input: something which can be opened by io/input-stream.
