markrad 0:cdf462088d13 22 * Minimal configuration for TLS 1.2 with PSK and AES-CCM ciphersuites
markrad 0:cdf462088d13 23 * Distinguishing features:
markrad 0:cdf462088d13 24 * - no bignum, no PK, no X509
markrad 0:cdf462088d13 25 * - fully modern and secure (provided the pre-shared keys have high entropy)
markrad 0:cdf462088d13 26 * - very low record overhead with CCM-8
markrad 0:cdf462088d13 27 * - optimized for low RAM usage
markrad 0:cdf462088d13 28 *
markrad 0:cdf462088d13 29 * See README.txt for usage instructions.
