/*
|
|
* 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.
