What it does
OpenKeychain is an open-source Android key-management application based on OpenPGP, with encryption and signing integrations for other apps.
OpenKeychain supplies OpenPGP key management and compatible-app integrations on Android. Its repository prominently states that active development has stopped; the maintainers say they may still apply reported security fixes and basic maintenance. Consider that status before adopting it for a new workflow. For an existing installation, verify correspondents' keys through an appropriate channel and keep your own key backup separate from the phone.
