ZipSign is a command line tool sign and verify ZIP archives.
ZipSign uses Cryptographic Message Syntax (CMS) to sign Zip archives. The signature is stored within the Zip archive's comment. See the "How it works" section on zipsign's GitHub page for further details.
Sign a Zip Archive
zipsign sign -f archive.zip -p private-key.pem -c cert.pem
Verify a previously signed Zip Archive
zipsign verify -f archive.zip -c cert.pem

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
To install zipsign, simply use the following command:
sudo snap install zipsign
Browse and find snaps from the convenience of your desktop using the snap store snap.
