 Functionality implemented include:
  - all above mentioned protocols, including support for client certificates
    (RFC 6101, RFC 2246, RFC 4346, RFC 5246, RFC 8446 - not complete)
+ - RSA, RSA-PSS and ECDSA certificates
  - RC4, 3DES-CBC, AES-CBC, AES-GCM and ChaCha20 ciphers (RFC 5246, RFC 6347,
    RFC 4492, RFC 5288, RFC 5289, RFC 7539, RFC 7905)
  - MD5, SHA1, SHA256 and SHA384 HMACs as well as AEAD mode of operation with
    GCM or Poly1305 authenticator
- - RSA, DHE_RSA and ECDHE_RSA key exchange
+ - RSA, DHE_RSA, ECDHE_RSA, ECDHE_ECDSA key exchange
  - full set of signature hashes (md5, sha1, sha224, sha256, sha384, sha512,
    rsa_pss_rsae_sha256, rsa_pss_rsae_sha384 and rsa_pss_rsae_sha512) for
