HTTPS Internet security related protocol work
how the protocol work
The encrypted version of
HTTP, HTTPS, stands for hypertext transfer protocol secure. It is used to
communicate securely across the internet or a network. Transport Layer Security
(TLS) or Secure Sockets Layer (SSL) is used to encrypt the communication protocol
(SSL).
This protocol uses a
mechanism known as asymmetric public key infrastructure, and it uses two
different keys
- Private
key: This key is available on the web server, which is managed by the
owner of a website.It decrypts the
information which is encrypted by the public key.
- Public
key: This key is available to everyone. It converts the data into an
encrypted form.
A handshake is used to set
up a connection between a client and server.To satisfy the client that it is
talking to the right server and that the parties have agreed on a cipher suite.
Both parties can use the
agreed algorithm and keys to send messages to each other once the connection is
established.The handshake will be broken into three main phases - Hello,
Certificate Exchange and Key Exchange.
