jarsigner Description
The jarsigner utility serves a dual function: it authenticates the signatures and verifies the integrity of signed JAR files while also enabling the signing of Java Archive (JAR) files. A digital signature consists of a sequence of bits derived from the data being signed along with the private key of a specific entity, which could be an individual or a corporation, among others. Much like a handwritten signature, a digital signature possesses several beneficial properties; its authenticity can be confirmed through a calculation that employs the public key linked to the private key used for generating that signature. Furthermore, it is intrinsically tied to the signed data, meaning it cannot validly represent a signature for different data, and any alteration to the signed data renders the signature unverifiable as genuine. This mechanism ensures that it cannot be counterfeited, provided that the private key remains confidential, thereby enhancing security in digital transactions and communications.

Keyfactor Signum
Keyfactor Signum ensures the safeguarding of sensitive keys, automates policy enforcement, and seamlessly integrates signing processes with your existing tools and build workflows. It allows for the generation and secure storage of private signing keys within a centralized, FIPS 140-2 certified hardware security module (HSM) hosted in the cloud. You can establish detailed access and usage policies for these private keys while also authenticating users and build servers involved in the signing process, all accompanied by a comprehensive audit trail. The solution works with platform-native signing tools to maintain the security of private signing keys without disrupting existing workflows. Additionally, it facilitates integration with signing tools through lightweight agents compatible with Windows and Linux, which can be quickly deployed on build servers or developer workstations. Furthermore, Keyfactor Signum generates key attestation to meet CA/B forum standards, ensuring that keys are both created and stored within an HSM, thereby enhancing security and compliance. This robust system not only streamlines the signing process but also significantly reduces the risk of key compromise.

apksigner
The apksigner utility, included in version 24.0.3 and later of the Android SDK Build Tools, enables users to sign APK files and ensure that the APK’s signature is valid across all Android platform versions compatible with that APK. This document provides a brief overview of utilizing the tool and acts as a guide to the various command-line parameters it supports. For a detailed explanation of the apksigner tool in the context of APK signing, refer to the complete documentation. The minimum Android framework API level that apksigner relies on to ensure the APK's signature can be verified is adjustable; higher values enhance security protocols during the signing process but may restrict the APK's compatibility with older devices. By default, the tool refers to the minSdkVersion attribute specified in the application’s manifest file, which determines its baseline compatibility. Users are encouraged to consider both security and compatibility when selecting the API level for their APKs.
