Handshake in TLS 1.3

This blog writes the takeaway notes of the TLS 1.3 handshake. To understand it, several basic crypto algorithms are required, such as SHA(security hash algorithm), DHE(Diffie-Hellman Exchange), KDF(key derivation function), DSA(digital signature algorithm) and AES. Moreover, understanding the PKI(public key infrastructure) is needed as well.

In this blog, the fundamental math formulas are not the focused parts. Instead, we focus on the whole workflow. The full details are stipulated by the rfc8446.
