From 81771ff2411a4cd1224c4b16e0b4247e71bba0de Mon Sep 17 00:00:00 2001 From: Nicolai Stange Date: Mon, 21 Feb 2022 13:11:00 +0100 Subject: lib/mpi: export mpi_rshift 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.
