+/**
+ * Minimal crypto 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
+ *
+ * To be used in conjunction with configs/config-suite-b.h. */
