;; A summary of ECC in TLS:
;; ECDH ECDSA uses long-term ECDH keys and ECDSA-signed certificates.
;; More specifically, the server's certificate must contain a long-term ECDH pub-
;; lic key signed with ECDSA, and hence a SERVER KEY EXCHANGE message
;; need not be sent. The client generates an ECDH key pair on the same elliptic
;; curve as the server's long-term public key and may send its own public key in
;; the CLIENT KEY EXCHANGE message. Both client and server then perform an
;; ECDH key exchange and use the result as the premaster secret.
;; ECDHE ECDSA uses ephemeral ECDH keys and ECDSA-signed certifi-
;; cates. More specifically, the server's certificate must contain an ECDSA public
;; key signed with ECDSA. The server sends it ephemeral ECDH public key
;; and a specification of the corresponding elliptic curve in a SERVER KEY EX-
;; CHANGE message. The parameters are digitally signed with ECDSA using
;; the private key corresponding to the public key in the server's certificate. The
;; client generates another ECDH key pair on the same curve and sends its pub-
;; lic key to the server in a C LIENT K EY E XCHANGE message. Again, both the
;; client and the server perform an ECDH key exchange and use the result as the
;; premaster secret.
;; ECDH RSA uses long-term ECDH keys and RSA-signed certificates. This
;; key exchange algorithm is essentially the same as ECDH ECDSA, except that
;; the server's certificate is signed with RSA instead of ECDSA.
;; ECDHE RSA uses ephemeral ECDH keys and RSA-signed certificates. This
;; key exchange algorithm is essentially the same as ECDHE ECDSA, except
;; that the server's certificate must contain an RSA public key authorized for
;; signing, and the signature in the SERVER KEY EXCHANGE message must be
;; generated with the corresponding private RSA key. Also, the server certificate
;; must be signed with RSA instead of ECDSA.
;; ECDH anon uses an anonymous ECDH key exchange without any authenti-
;; cation. This basically means that no signature must be provided, and hence
;; no certificate must be in place. The ECDH public keys are exchanged in
;; SERVER KEY EXCHANGE and CLIENT KEY EXCHANGE messages.
