SignPath Code Signing Integration

This document describes how Ferrite uses SignPath for Windows code signing.

Overview

Ferrite uses SignPath for code signing Windows artifacts. SignPath provides free code signing for open source projects, which helps:

• Prevent Windows Defender false positives (e.g., Trojan:Win32/Bearfoos.B!ml)
• Establish trust with users downloading the application
• Comply with Windows SmartScreen requirements

Configuration Files

Artifact Configuration

Location: .signpath/artifact-configuration.xml

Defines the structure of artifacts to sign:

<artifact-configuration xmlns="http://signpath.io/artifact-configuration/v1">
  <zip-file>
    <zip-file path="ferrite-portable-windows-x64.zip">
      <pe-file path="ferrite.exe" />
    </zip-file>
    <msi-file path="ferrite-windows-x64.msi">
      <pe-file path="ferrite.exe" />
    </msi-file>
  </zip-file>
</artifact-configuration>

GitHub Workflow

Location: .github/workflows/release.yml

The workflow:

1. Builds Windows artifacts (build-windows job)
2. Signs artifacts via SignPath (sign-windows job)
3. Creates release with signed artifacts (release job)

Required Secrets

Add these secrets to your GitHub repository:

Secret	Description
SIGNPATH_API_TOKEN	API token from SignPath dashboard (user with submitter permissions)
SIGNPATH_ORGANIZATION_ID	Your SignPath organization ID

SignPath Dashboard Setup

1. Organization Setup

1. Accept the invitation to your SignPath OSS organization
2. Log in at https://app.signpath.io

2. Project Configuration

1. Create a project named ferrite
2. Add the artifact configuration (copy from .signpath/artifact-configuration.xml)
3. Create a signing policy named release-signing

3. Trusted Build System

1. Add the predefined "GitHub.com" trusted build system to your organization
2. Link it to the Ferrite project
3. Install the SignPath GitHub App and allow access to the repository

Testing

With Self-Signed Certificate

For initial testing, SignPath provides a self-signed test certificate:

1. Create a test tag: git tag v0.2.5-hotfix.3-test && git push --tags
2. Verify the workflow completes successfully
3. Download and test the signed artifacts
4. Delete the test release if needed

With Production Certificate

After successful testing:

1. Contact SignPath to request the production certificate
2. SignPath will review your setup and import the certificate
3. Future releases will use the production certificate automatically

Troubleshooting

Signing Request Failed

• Check that secrets are configured correctly
• Verify the artifact configuration matches your artifact structure
• Check SignPath dashboard for error details

Artifact Not Found

• Ensure artifacts are uploaded with actions/upload-artifact@v4
• Verify the artifact ID is passed correctly to SignPath action

Timeout Errors

• SignPath signing can take several minutes
• Default timeout is 600 seconds (10 minutes)
• Increase wait-for-completion-timeout-in-seconds if needed
