|

26 | *
|
---|
27 | * Distinguishing features:
|
---|
28 | * - no RSA or classic DH, fully based on ECC
|
---|
29 | * - optimized for low RAM usage
|
---|
30 | *
|
---|
31 | * Possible improvements:
|
---|
32 | * - if 128-bit security is enough, disable secp384r1 and SHA-512
|
---|
33 | * - use embedded certs in DER format and disable PEM_PARSE_C and BASE64_C
|
---|
34 | *
|
---|
35 | * See README.txt for usage instructions.
