Are you looking for command line usage instead?
To manually build the binaries, see building from source.
The desktop app installs the command line on first run:
ln -s /Applications/Keys.app/Contents/Resources/bin/keys /usr/local/bin/keys
brew tap keys-pub/tap brew install keys
The scoop install will conflict with the desktop app. Fix is in progress.
The desktop app ships with the command line utilities, you can add it to your %PATH%:
To install via scoop:
scoop bucket add keys.pub https://github.com/keys-pub/scoop-bucket scoop install keys
Add keys.pub apt repository:
echo "deb https://storage.googleapis.com/aptly.keys.pub current main" \ | sudo tee -a /etc/apt/sources.list.d/keys.list
Add the keys apt signing public key:
wget -qO - https://storage.googleapis.com/aptly.keys.pub/keys.asc | sudo apt-key add -
sudo apt-get update sudo apt-get install keys
