From 93cc74e078eed8735585e5687903727bcfbcc8b4 Mon Sep 17 00:00:00 2001 From: Joy Latten Date: Wed, 12 Dec 2007 20:24:22 +0800 Subject: [CRYPTO] tcrypt: Add CCM vectors This patch adds 7 test vectors to tcrypt for CCM. The test vectors are from rfc 3610. There are about 10 more test vectors in RFC 3610 and 4 or 5 more in NIST. I can add these as time permits. I also needed to set authsize. CCM has a prerequisite of authsize.
