Enabling required commit signing

Before enabling required commit signing on a branch, you must first set the branch up as a protected branch. For more information, see "Configuring protected branches."

You can automatically enforce protected branch settings for some or all branches in your repository. For more information, see "Configuring protected branches."

1. On GitHub Enterprise Server, navigate to the main page of the repository.
2. Under your repository name, click Settings.
   
3. In the left menu, click Branches.
   
4. Next to "Branch protection rules", click Add rule.
   
5. Under "Branch name pattern", type the branch name or pattern you want to protect.
   
6. Select Require signed commits.
   
7. Optionally, select Include administrators. This enforces the required signed commits on the repository administrators.
   
8. Click Create.
