OBS
Open Broadcaster Software®️
Summary
The codesigning certificate used for OBS Studio will be updated for OBS Studio 31.1. As part of this we will also have to switch the certificate used to sign the game capture hook, which may require updates to anti-cheat solutions that specifically exempt the current certificate.
Timeline
- 30.1 used the old RSA certificate
- 30.2 used a dual-signed game capture hook that contains both the old RSA and new ECC certificate (in that order)
- 31.0 used only the new ECC certificate
- 31.1 will use a dual-signed game capture hook that contains both a new RSA certificate and the ECC certificate introduced with 30.2 (in that order)

Testing Instructions
This section is intended for game and anti-cheat developers, not end users.
If you are using an off-the-shelf anti-cheat solution such as Easy Anti-Cheat or BattlEye you may check the table above for the current status. You should not have to take any further action if the configuration currently being used is already working. Please let us and your anti-cheat vendor know if you are running into problems.
If you wish to test your game/anti-cheat solution against the new certificate please follow the following steps:
- Download our 31.1.0 beta build that is signed with the new certificate
1.1. Installer (recommended)
1.2. Portable ZIP - Install/unzip the new build
2.1. (If not using the installer) Clear%PROGRAMDATA%\obs-studio-hook - Run the new build
3.1. (If not using the installer) Run the build with administrative permissions at least once - Try to capture a game
New Certificates
The new RSA-based certificate is issued by DigiCert to "OBS Project, LLC". This is only used to dual-sign the OBS Studio game capture hook files. The contents of the public certificate are as follows:
