Research direction

Start by locating the Crypto_AOS CBC cipher calls and their libgcrypt integration, then review how AOS and TM handle CBC padding limits and CCM coverage. Check the existing unit-test area for libgcrypt and determine what CCM cases are missing. Done means the required calls and padding behavior are reviewed or corrected and CCM unit tests are present.
