        echo "Error: No files provided" >&2
        return 1
    }
    sha256sum "${files[@]}" 2>/dev/null | sort | sha256sum | cut -d' ' -f1
}

How can I use SSH for Git on a network that blocks outbound SSH

In Github is easy, just convert this

git clone [email protected]:rtyley/small-test-repo.git

to this

git clone ssh://[email protected]:443/rtyley/small-test-repo.git

You will be able to clone the repository using SSH over port 443, which is typically open on most networks.
