Tobias Frauenschläger eb8ba6124e Support TLS 1.3 ECC Brainpool authentication
This also fixes TLS 1.2 authentication to only succeed in case the
brainpool curve was present in the supported_groups extension.

Tobias Frauenschläger a462398387 Support Brainpool ECC curve TLS 1.3 key exchange
When both TLS 1.3 and Brainpool curves are enabled, three new groups can
be used for the ECDHE key exchange according to RFC 8734:
* WOLFSSL_ECC_BRAINPOOLP256R1TLS13 (31)
* WOLFSSL_ECC_BRAINPOOLP384R1TLS13 (32)
* WOLFSSL_ECC_BRAINPOOLP512R1TLS13 (33)

Also ensure that the existing TLS 1.2 curves are sent properly.

The TLS client application is updated to support handshakes via
Brainpool curves using the new argument "--bpKs".

Sean Parkinson dc86dad26b ECC key load: fixes
asn.c:
  Return the curve OID sum with alg_id for ECC keys.
ssl_load.c:
Don't permanently strip the PKCS#8 information as it contains the
curve OID.

David Garske 10f459f891 Added TLS v1.2 and v1.3 test cases for ECC Koblitz and Brainpool curves (both server auth and mutual auth). Cipher suites: ECDHE-ECDSA-AES128-GCM-SHA256, ECDH-ECDSA-AES128-GCM-SHA256 and TLS13-AES128-GCM-SHA256. 2020-11-10 09:47:36 -08:00
