Subject: [PATCH 14/18] lib/mpi: export mpi_rshift
Date: Wed, 1 Dec 2021 01:48:54 +0100 [thread overview]
Message-ID: <20211201004858.19831-15-nstange@suse.de> (raw)
In-Reply-To: <20211201004858.19831-1-nstange@suse.de>
A subsequent patch will make the crypto/dh's dh_is_pubkey_valid() to
calculate a safe-prime groups Q parameter from P: Q = (P - 1) / 2. For
implementing this, mpi_rshift() will be needed. Export it so that it's
accessible from crypto/dh.
