Subject: [PATCH v2] crypto/ipsec_mb: use new ipad/opad calculation API
Date: Sun, 11 Feb 2024 19:10:38 +0000 [thread overview]
Message-ID: <20240211191038.863120-1-brian.dooley@intel.com> (raw)
In-Reply-To: <20231214164135.2193863-1-brian.dooley@intel.com>
IPSec Multi-buffer library v1.4 added a new API to
calculate inner/outer padding for HMAC-SHAx/MD5.
