Subject: [PATCH 08/17] lib/crypto: sha3: Drop unfinished SHAKE support from gen-hash-testvecs.py
Date: Sun, 19 Oct 2025 17:50:29 -0700	[thread overview]
Message-ID: <20251020005038.661542-9-ebiggers@kernel.org> (raw)
In-Reply-To: <20251020005038.661542-1-ebiggers@kernel.org>

The SHAKE testing doesn't actually use gen-hash-testvecs.py, so remove
the unfinished SHAKE support from it.
