00022  * Minimal configuration for TLS NSA Suite B Profile (RFC 6460)
00023  *
00024  * Distinguishing features:
00025  * - no RSA or classic DH, fully based on ECC
00026  * - optimized for low RAM usage
00027  *
00028  * Possible improvements:
00029  * - if 128-bit security is enough, disable secp384r1 and SHA-512
00030  * - use embedded certs in DER format and disable PEM_PARSE_C and BASE64_C
00031  *
00032  * See README.txt for usage instructions.
