Subject: [RFC 10/11] hornet: Add a light skeleton data extractor scripts
Date: Wed, 10 Dec 2025 18:12:05 -0800 [thread overview]
Message-ID: <20251211021257.1208712-11-bboscaccy@linux.microsoft.com> (raw)
In-Reply-To: <20251211021257.1208712-1-bboscaccy@linux.microsoft.com>
These script eases light skeleton development against Hornet by
generating a data payloads which can be used for signing a light
skeleton binary using gen_sig.
