Signing certificate · SHA-256

Every Firedown APK, on every channel, is signed with this certificate. Android installs an update only if it carries the same signature, so one check is enough.

  • On your phone: AppVerifier checks the installed app against these two lines.
  • On a computer: apksigner verify --print-certs app-release.apk prints the same fingerprint, in lower case and without colons.
  • In-app updates are checked before they install: the file against the SHA-256 we publish for it, and its signature against the installed app’s.

Same APK, same signing key on every channel. Verify any build's SHA-256 against GitHub releases.
