Protocol: SSL Alarm Protocol message is composed of severity level and warning code two parts1. Severity level (Alertlevel)1Fatal Fatal level alarm is a fatal level alarm, it requires both parties to take emergency measures, and terminate the session, while eliminating their own buffer corresponding session record2waming Warning Level alarm is the processing of warning level alarm, usually the communication both sides only log record, it does not aff

I. SSL handshake has three purposes:1. The client and server need to agree on a set of algorithms used to protect data;2. They need to establish a set of encryption keys used by those algorithms;3. Handshakes can also be used to authenticate the client.
Ii. SSL handshake process:1. The client sends the list of algorith

Handshake process of the SSL protocol
To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. The SSL protocol uses both public key encryption technology (asymmet
I. The handshake process of SSL/TLS
In the SSL/TLS handshake process, the client and the server need to exchange parameters, the specific process is as follows: The client provides the various cipher suites that it supports (including cryptographic algorithms and hash functions) from which the server chooses itself and

You may find it more complicated than it is in practical use. Fortunately, the good pioneers implemented the layer in the operating system or related software, and a nasty name called
The SSL/TLS handshake process can be divided into two types:
1) SSL/TLS two-way authentication, that is, both sides will be mutual authentication, that is, the exchange of certificates between the two.2) SSL/TLS one-way authentication, the client authenticates the server side, and the server does not authenticate the c
