Recognising F-Droid apps from APK signature

Are all F-droid apps signed in apk by F-Droid(Not PGP signature).

There is an app called APK Analyzer that shows details about signature including Source(Play, Amazon etc).

Currently the author wants to add F-Droid to sources, but we want to know if F-Droid signs APKs using a single signature.(Not PGP).

Most of apps on F-Droid main repo are signed by F-Droid, but some are built reproducibly and have authors’ signatures.


APK Analyzer is nice. Would be cool to have it on F-Droid.
