The rules for which digest algorithms are accepted by the Android platform for APK signatures and OTA update package signatures are different. For example, the set of digest algorithms accepted for APK signatures depends on the signing key algorithm and the platform's API Level. Whereas the set of digest algorithms accepted for OTA update package signatures by Recovery depends on the list produced by the build system, which in turn produces the list based on the key algorithm and digest used in the signing certificate. To reflect this reality, this refactoring CL explicitly separates signapk's logic for choosing the digest algorithm to use for v1 signing from its logic for choosing the digest algorithm to use for OTA update package signing.
