What is apkverifier
apkverifier is:
apkverifier is a simple command line tool that verifies the
signatures on Android APK binaries. It can verify APK Signature
scheme v1, v2 and v3 and passes Google apksig’s testing suite. It
should support all algorithms and downgrade attack protection.
Because Android can handle even broken x509 cerficates and ZIP files,
apkverifier is using the ZipReader from apkparser package and vendors
crypto/x509 in internal/x509andr and github.com/fullsailor/pkcs7
(https://github.com/fullsailor/pkcs7) in the fullsailor/pkcs7 folder.
The last two have some changes to handle some
not-entirely-according-to-spec certificates.
