Verifying Downloaded APKs

All APKs published on the GitHub Releases page (including the Lite variant) are signed with the same certificate. To verify a download before installing it:

apksigner verify --print-certs KeepAlive.apk

The certificate SHA-256 digest should be:

c45567b712d6fd7979df14f66f8a5c25859ee223e1f07e915a7eee201c14baef

Builds installed from an app store may be signed differently (for example by Google's Play App Signing); this digest applies to the APKs from GitHub Releases.
