# Changelog

All notable changes to OpenMausBot are documented here. The format is based on
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project
adheres to [Conventional Commits](https://www.conventionalcommits.org/).

## [Unreleased]

## [0.1.27]

### Fixed
- **Windows build: extract Android Platform Tools under git-bash.** `scripts/prepare-android-tools.mjs`
now tries `unzip` and falls back to `tar`, and normalizes absolute Windows paths to
MSYS form (`C:\x` → `/c/x`) so `pnpm build:android-tools` / `pnpm package:win`
succeed on a stock git-bash install instead of failing with
`tar: Cannot connect to C: resolve failed`. ([#317](https://github.com/milind-soni/OpenMausBot/pull/317))

### Added
- **Reproducible Windows code-signing step.** `scripts/sign-win.ps1` signs the NSIS
installer and the inner `OpenMausBot.exe` with any PFX — a self-signed cert
Comment thread
coderabbitai[bot] marked this conversation as resolved.
(`build/omb-selfsigned.pfx`, gitignored) for pipeline verification, or a real
CA-issued Authenticode cert supplied via `CSC_LINK`/`CSC_KEY_PASSWORD`.

Align the documented certificate variables with scripts/sign-win.ps1.

scripts/sign-win.ps1 reads OMB_CERT_FILE and OMB_PFX_PASSWORD, not CSC_LINK or CSC_KEY_PASSWORD. The release workflow does not invoke the script or map these variables. Update the documentation and workflow so the CA-issued certificate reaches the signing step.

Microsoft SmartScreen reputation valid OV EV binaries warnings until reputation accumulates EV certificates no longer bypass process

💡 Result:

As of August 2026, Microsoft Defender SmartScreen no longer grants automatic reputation or bypasses to applications based on Extended Validation (EV) code signing certificates [1][2][3]. While EV certificates were historically associated with immediate trust, that behavior has been removed [1][4]. Key points regarding SmartScreen reputation: 1. EV vs. OV Equivalence: Both EV and OV (Organization Validation) certificates are treated equally by SmartScreen [5][3]. Neither provides an instant bypass for reputation warnings [1][2]. 2. Organic Reputation Building: SmartScreen reputation is built organically over time [2][6]. It is based on a combination of signals, including the file hash (SHA256), the publisher identity, and the accumulation of positive telemetry from users downloading and running the signed file without security incidents [1][5][7]. 3. Impact of Certificate Renewal: Because reputation is tied to specific signing keys and publisher identities, renewing an EV or OV certificate (which generates a new thumbprint/key) effectively treats the publisher as a new entity for reputation purposes [6][8]. Existing reputation does not automatically transfer to a new certificate, leading to a period where new binaries may trigger warnings until sufficient new telemetry is gathered [6][8]. 4. No Manual Bypass: There is no supported mechanism, engineering override, or "trusted list" to manually request, restore, or boost reputation for a specific certificate or binary [5][6][8]. 5. Microsoft Store Exception: Applications published and distributed through the Microsoft Store are re-signed by Microsoft, which grants them full, immediate reputation and prevents SmartScreen warnings [1]. In summary, code signing remains a critical security best practice for establishing publisher identity and ensuring compatibility with features like Windows Smart App Control, but it no longer serves as a shortcut to avoid SmartScreen warnings [1][7][4]. Software publishers must rely on organic adoption to build and maintain trust for their binaries [1][6].

Qualify the SmartScreen guarantee.

A CA-issued Authenticode certificate establishes publisher identity but does not guarantee a SmartScreen-clean install. SmartScreen can warn for valid OV and EV signatures until reputation accumulates. Update the note accordingly.

#### Code-signing the Windows build

`pnpm package:win` produces an **unsigned** installer (SmartScreen flags it as
"unknown publisher"). Sign it with Authenticode after the build:

```sh
# self-signed test cert (pipeline verification only — still trips SmartScreen)
pwsh scripts/sign-win.ps1

# real CA-issued cert (clean SmartScreen install)
CSC_LINK=path/to/cert.pfx CSC_KEY_PASSWORD=**** pwsh scripts/sign-win.ps1
```

`scripts/sign-win.ps1` signs both `release/OpenMausBot-<ver>-setup.exe` and the
inner `OpenMausBot.exe` with an RFC-3161 timestamp (DigiCert), so the signature
outlives the cert. A self-signed cert validates only on machines that trust its
root; for a SmartScreen-clean install use a CA-issued Authenticode certificate
and set `win.certificateFile` / `CSC_*` in `electron-builder.yml`.

Pass the certificate to the post-build signer with the variables it reads.

scripts/sign-win.ps1 reads OMB_CERT_FILE and OMB_PFX_PASSWORD, not CSC_LINK and CSC_KEY_PASSWORD. The current command therefore falls back to the self-signed certificate in a POSIX shell. It is not valid PowerShell environment-variable syntax.

$env:OMB_CERT_FILE = 'path\to\cert.pfx'
$env:OMB_PFX_PASSWORD = Read-Host 'PFX password'
pwsh scripts/sign-win.ps1

Keep CSC_* documented for electron-builder's native signing path. Document pnpm package:win:signed if it is the intended end-to-end workflow.

Run the signing step in the Windows packaging workflow.

The supplied package-win.yml path runs pnpm package:win but does not run pwsh scripts/sign-win.ps1. The default build/omb-selfsigned.pfx is also ignored by .gitignore, and this script does not create it. Therefore a clean CI checkout cannot perform the documented self-signed pipeline verification.

Add certificate generation or CI-secret provisioning and invoke the script, or document this workflow as local-only.

electron-builder documentation afterSign hook runs before distributable is created

💡 Result:

Yes, according to the official electron-builder documentation, the afterSign hook is designed to run after the application has been signed but before the distributable (e.g., DMG, NSIS, installer) is created [1][2][3]. While early versions of electron-builder had reported issues where the afterSign hook appeared to trigger before the code signing process [4][5], these were identified as bugs that have been addressed in later versions (e.g., via improvements to the macPackager signApp implementation) [6]. Key characteristics of the afterSign hook: 1. Timing: It executes after the signing process is complete, provided that signing was actually performed [1]. It will not fire if signing is skipped (e.g., if no certificate is configured) [1]. 2. Purpose: It is primarily intended for tasks that require the application to be signed, such as custom macOS notarization workflows [2][3][7]. 3. State of filesystem: At the point this hook runs, the staging directory contains the fully signed application bundle, and the final distributable files have not yet been generated [1][2]. If you are experiencing behavior where the hook seems to run before signing, ensure you are using a recent version of electron-builder [6]. You can also verify the hook's execution timing by placing console logs within your hook script [4].

Sign the application before NSIS creates the installer.

The documented flow runs scripts/sign-win.ps1 after pnpm package:win, and .github/workflows/package-win.yml does not invoke it. NSIS can therefore embed unsigned application bytes.

Configure electron-builder to sign the application during packaging. Use an enabled afterSign hook for custom signing before distributables are created. If post-build signing changes the installer, regenerate release/latest.yml hashes and sizes and release/*.exe.blockmap before upload.

In `@scripts/sign-win.ps1` around lines 42 - 46, Configure electron-builder to
invoke the existing custom signing flow through an enabled afterSign hook during
packaging, ensuring application binaries are signed before NSIS creates
distributables. Update the packaging workflow to use this hook rather than
relying on a post-package scripts/sign-win.ps1 step, and regenerate release
metadata hashes, sizes, and executable blockmaps if post-build signing modifies
installer artifacts.
