| /* |
| * Minimal configuration for TLS NSA Suite B Profile (RFC 6460) |
| * |
| * Distinguishing features: |
| * - no RSA or classic DH, fully based on ECC |
| * - optimized for low RAM usage |
| * |
| * Possible improvements: |
| * - if 128-bit security is enough, disable secp384r1 and SHA-512 |
| * - use embedded certs in DER format and disable PEM_PARSE_C and BASE64_C |
| * |
| * See README.txt for usage instructions. |
