| * 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. |
