* Minimal configuration for TLS 1.2 with PSK and AES-CCM ciphersuites * Minimal configuration for TLS 1.2 with PSK and AES-CCM ciphersuites
* Distinguishing features:
* - no bignum, no PK, no X509
* - fully modern and secure (provided the pre-shared keys have high entropy)
* - very low record overhead if using the CCM-8 suites
* - optimized for low RAM usage

* See README.txt for usage instructions. * See README.txt for usage instructions.
