Microsoft and SanDisk sign APKs with a X.509 certificate chain of
trust, so there are actually three certificates included. apksigner
only cares about one certificate and ignores the other certificates in
the chain.
The correct values come from:
apksigner verify --print-certs 883cbdae7aeb2e4b122e8ee8d89966c7062d0d49107a130235fa220a5b994a79.apk
X.509 certificates are machine generated and just data, so are not
copyrightable. So I included SANAPPSI.* directly.
