/*
* 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.
