Go to the documentation of this file.
1 /*
2  * Minimal configuration for TLS 1.2 with PSK and AES-CCM ciphersuites
3  * Distinguishing features:
4  * - no bignum, no PK, no X509
5  * - fully modern and secure (provided the pre-shared keys have high entropy)
6  * - very low record overhead with CCM-8
7  * - optimized for low RAM usage
8  *
9  * See README.txt for usage instructions.
