Code Signing Platform Guide

Code signing works differently across Windows, Java, macOS, Adobe, Android, iOS, and other software ecosystems. Each platform can use its own signing technology, certificate or key model, verification process, and distribution rules.

This page brings the major Code Signing Solution platform resources together so you can identify the right signing path for the software you ship.

How the Code Signing Platforms Differ

The biggest difference is not the idea of a digital signature. It is the way each ecosystem defines the signing identity, signature format, trust relationship, and release process.

Signing identityMay be a CA-issued certificate, an Apple signing identity, or an application-specific key and certificate.
Signing formatAuthenticode, JAR signing, Apple code signing, Android application signing, and other platform-specific formats.
VerificationEach platform applies its own integrity, identity, certificate, trust, and distribution checks.
DistributionDesktop installers, scripts, archives, application stores, notarization, and platform-controlled release paths can differ.

One Security Strategy, Multiple Signing Models

A company shipping software for several ecosystems does not need to force every product into one certificate model. The stronger approach is to keep each platform's required signing identity while standardizing the security controls around signing.

Certificate inventory, private-key protection, CI/CD permissions, release approvals, verification, audit logging, expiration monitoring, and incident response can be managed as one organizational process.

Platform credentials

Maintain separate Windows certificates, Apple identities, Android signing keys, Java signing material, and any other platform-specific credentials required by your products.

Central signing controls

Apply consistent policies for who can sign, which environments can request signatures, and how production signing events are logged and reviewed.

Release verification

Verify the signed artifact before distribution and confirm that the signature, identity, certificate chain, and platform-specific requirements are in the expected state.

Which Code Signing Guide Should You Use?

Start with the software or artifact you are preparing to release. The correct guide is determined by the target platform and signing technology, not simply by the fact that the software is digitally signed.

From Artifact to Platform Trust

The same high-level release sequence appears across many ecosystems, but the implementation changes at the platform-signing stage. That is why a platform-specific guide is useful even when the underlying security goal is similar.
