What is SSL

SSL (Secure Sockets Layer) is a mechanism (protocol) for encrypting data sent and received over the Internet. It is a protocol that encrypts and protects personal information on the Internet.

SSL is used in various situations, such as browsing websites and sending and receiving e-mail.

SSL Process Flow

The SSL process flow is as follows

1. The client requests SSL communication from the server.
2. The server sends a certificate and public key to the client.
3. The client encrypts the symmetric key with the public key and sends it to the server.
4. Both parties communicate by encrypting and decrypting with the shared symmetric key.

SSL prevents data eavesdropping and tampering by encrypting important data such as personal and credit card information as it is sent and received.

SSL is an indispensable mechanism for secure communication over the Internet.
