|  | /* | 
|  | * 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. |
