ECDH parameters in TLS 1.3 – Elliptic Curves

8.5.7 ECDH parameters in TLS 1.3 Both server Alice and client Bob encode their ECDH parameters in the KeyShare structure, in the key˙exchange opaque field of a KeyShareEntry. When elliptic curves secp256r1, secp384r1, or secp521r1 are used, the key˙exchange field stores the serialized value of the UncompressedPointRepresentation structure shown in Listing 8.3. Listing 8.3: Uncompressed…
