The kubeseal utility uses asymmetric crypto to encrypt secrets that only the cluster can decrypt. These encrypted secrets are encoded in a SealedSecret resource, once unsealed this will produce a normal Secret inside the cluster.

snap install sealed-secrets-kubeseal-nsg

sudo snap alias sealed-secrets-kubeseal-nsg kubeseal

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Kubuntu 16.04 LTS (Xenial Xerus) or later, including Kubuntu 18.04 LTS (Bionic Beaver) and Kubuntu 18.10 (Cosmic Cuttlefish), you don’t need to do anything. Snap is already installed and ready to go.
Versions of Kubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf) don’t include snap by default, but snap can be installed from the command line as follows:
sudo apt update
sudo apt install snapd
