How To Install libapksig-java on Kali Linux
Introduction
In this tutorial we learn how to install libapksig-java
on Kali Linux.
What is libapksig-java
libapksig-java is:
apksig is a project which aims to simplify APK signing and checking whether APK’s signatures should verify on Android. apksig supports JAR signing (used by Android since day one) and APK Signature Scheme v2 (supported since Android Nougat, API Level 24).
The key feature of apksig is that it knows about differences in APK signature verification logic between different versions of the Android platform. apksig can thus check whether a signed APK is expected to verify on all Android platform versions supported by the APK. When signing an APK, apksig will choose the most appropriate cryptographic algorithms based on the Android platform versions supported by the APK being signed.
apksig library offers three primitives:
ApkSigner which signs the provided APK so that it verifies on all Android platform versions supported by the APK. The range of platform versions can be customized if necessary.
ApkVerifier which checks whether the provided APK is expected to verify on all Android platform versions supported by the APK. The range of platform versions can be customized if necessary.
(Default)ApkSignerEngine which abstracts away signing an APK from parsing and building an APK file. This is useful in optimized APK building pipelines, such as in Android Plugin for Gradle, which need to perform signing while building an APK, instead of after. For simpler use cases where the APK to be signed is available upfront, the ApkSigner above is easier to use.
NOTE: Some public classes of the library are in packages having the word ??internal?? in their name. These are not public API of the library. Do not use .internal. classes directly.
