Subject: [PATCH 07/11] lib/crypto: md5: Use hmac_md5_zeroize_ctx() instead of memzero_explicit()
Date: Thu, 13 Aug 2026 15:49:45 +0200 [thread overview]
Message-ID: <20260813134953.979481-8-thuth@redhat.com> (raw)
In-Reply-To: <20260813134953.979481-1-thuth@redhat.com>
From: Thomas Huth <thuth@redhat.com>
It's only cosmetics, but since we have the new hmac_md5_zeroize_ctx()
function anyway, we can also use it here.
