git-remote-gittuf

Alongside the gittuf binary, gittuf ships with a custom remote transfer protocol binary, implementing Git's remote-helper interface. We call this the transport binary, named git-remote-gittuf.

It's an easy way to get started with using gittuf on your repository, as it takes care of the following common operations for you:

• Creating RSL entries upon pushing your changes
• Fetching gittuf metadata when pulling changes

[!NOTE] The transport does not perform the steps needed to initialize a gittuf repository (i.e. setting up root of trust, policy, etc.). These steps must be done manually for new repositories (see the get started guide.

The gittuf transport supports both HTTPS and SSH remotes.

How to Install

You can install the transport by either using pre-built binaries, or building from source if you wish.

Pre-built binaries

This repository provides pre-built binaries for the transport that are signed and published using GoReleaser. The signature for these binaries are generated using Sigstore, using the release workflow's identity. Refer to the instructions in the get started guide to verify the signature for the transport binary.

If you are on Windows, you may also install the transport from Winget by running:

winget install gittuf.git-remote-gittuf

Building from source

Alternatively, the transport can be built from source. Running make in the project's top-level directory will compile the transport and place it in your GOBIN.

How to Use

Once it's installed, using the custom transport is simple; you'll need to add the gittuf:: prefix to the repository URL. How to do this depends on the repository you'd like to use it for.

Using with a fresh git clone

When running git clone, add gittuf:: to the beginning of the URL of the repository. For example,

• gittuf::git@github.com:gittuf/gittuf, if you're using SSH
• gittuf::https://github.com/gittuf/gittuf, if you're using HTTPS

Using with an existing repository

In this case you'll need to set the remote for your repository (most likely origin):

# For SSH
git remote set-url origin gittuf::git@github.com:gittuf/gittuf

# For HTTPS
git remote set-url origin gittuf::https://github.com/gittuf/gittuf
