* 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 with CCM-8
|
|
* - optimized for low RAM usage
|
|
*
|
|
* See README.txt for usage instructions.
