Official BorgMate download packages are signed with GPG, and automatic updates install only releases whose manifest carries that signature; the installed binaries themselves are not signed. The signatures are available in our GitHub releases. GPG signing key fingerprint: 2D0B01C4BDAAF32BA376AE1E793239019CE4CF26.
Automatic updates verify each downloaded package against the signed SHA-256 before installation, including packages already cached locally.

global.jsonrequires exactly this version) - BorgBackup 1.4.x, 1.4.5 or newer recommended

A Release build of the same commit produces the same BorgMate.dll byte for byte on Windows, macOS and Linux.
To rebuild a release, check out its tag in a clean clone and publish it for the platform you want to compare:
git clone https://github.com/oddbit-io/borgmate.git
cd borgmate
git checkout v<version>
dotnet publish BorgMate/BorgMate.csproj -c Release -r <rid> --self-contained true -o outStarting with 1.3.1, every file in out matches the official build, except BorgMate.deps.json and BorgMate.runtimeconfig.json: the SDK writes them with the line endings of the build machine.
The installers and update packages are not reproducible yet.
BorgMate release numbers follow Semantic Versioning 2.0.0.
