    Hello Department of Energy,

    I cannot find that you are an existing customer of ours, so we cannot fulfill this request.

    libcurl is a product we work on. It is open source and licensed under an MIT-like license in which the distribution and use conditions are clearly stated.

    If you contact [email protected] we can remedy this oversight and can then arrange for all the paperwork and attestations you need.

I imagine for the DoE to get the guarantees they want it might expand somewhat.
