TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
алгоритм Диффи-Хеллмана на эллиптических кривых, аутентификация сервера будет производится с помощью ECDSA, а в качестве алгоритма шифрования трафика будет использоваться AES с длиной ключа 128 бит в режиме GCM. В качестве алгоритма MAC используется SHA256.
Прикольно))
И на чём вы это всё собрались делать ? ))
