[PATCH v2 0/1] MR701: wineboot: Generate ProductId from host's machine id.

[Torge Matthies (＠tmatthies)]

I could have used CryptStringToBinaryA for the hex->bin conversion, but that would add another import to wineboot.

This patch was created by me on request from Alexandr Oleynikov of the Lutris project back in September of 2020.

[PATCH v2 1/1] wineboot: Generate ProductId from host's machine id.

[Torge Matthies]

From: Torge Matthies <tmatthies(a)codeweavers.com>

Uses a hash of the systemd or dbus machine-id to generate a stable
product id. If neither file is found (e.g. on macOS), it will use all
zeroes for the hash input.
