What is SSL explain with diagram?

Table of Contents

Secure Sockets Layer (SSL) is a computer networking protocol for securing connections between network application clients and servers over an insecure network, such as the Internet. SSL establishes a secure link between a web server and browser to transmit data.

What are the protocols used in SSL?

SSL protocol is located between the application layer and transport layer. There are three subprotocol Handshake Protocol, Record Protocol and Alert Protocol. These three SSL protocols constitute the overall working of Secure Socket Layer.

What are the four SSL protocols?

The SSL protocol stack includes the following protocols:

SSL record protocol at the lower layer.
SSL handshake protocol, SSL change cipher spec protocol, and SSL alert protocol at the upper layer.

What is the SSL protocol stack?

The SSL protocol consists of two layers of protocols: the SSL record protocol at the lower layer and the SSL handshake protocol, change cipher spec protocol, and alert protocol at the upper layer.

What layer does SSL operate at?

SSL operates at the presentation layer in the OSI model (Layer6). See reference The TCP/IP guide, M. Kozierok, page 111. “Protocols at this layer take care of manipulation tasks that transform data from one representation to another, such as translation, compression and encryption.

Does SSL use TLS?

SSL refers to Secure Sockets Layer whereas TLS refers to Transport Layer Security. Basically, they are one and the same, but, entirely different. How similar both are? SSL and TLS are cryptographic protocols that authenticate data transfer between servers, systems, applications and users.

Is SSL a Layer 7?

-SSL/TLS can arguably be called a Transport protocol for the “application data” that the webbrowser is trying to display to the end-user. This puts it at around Layer 6-7 depending on how you want to argue for “presentation” vs “application” layer.

What is the main difference between SSL and TLS?

SSL is a cryptographic protocol that uses explicit connections to establish secure communication between web server and client. TLS is also a cryptographic protocol that provides secure communication between web server and client via implicit connections. It’s the successor of SSL protocol.

What OSI layer is https?

While HTTP works in the application layer of the OSI model, HTTPS works in the transport layer of the OSI model.

What OSI layer is HTTPS?

What OSI layer is SSL?

SSL operates at the presentation layer in the OSI model (Layer6).

What is SSL protocol?

Introduction to SSL Protocols SSL stands for Secure Socket Layer protocol, is an Internet protocol used for exchanging the information over a web browser and web server in a secure manner, provides two basic services like authentication and confidentiality. SSL protocol is located between the application layer and transport layer.

What are the steps involved in SSL client and server communication?

Let’s understand the above steps: The client sends a “client hello” message. This includes the client’s SSL version number, cipher settings, session-specific data and other information that the server needs to communicate with the client using SSL. The server responds with a “server hello” message.

What are the cryptographic algorithms used in SSL?

Before diving into the topic, here are some cryptographic algorithms used in the SSL protocol that you need to understand. Encryption is a process of converting plain text into an intelligible format (Ciphertext). Symmetric encryption ( also known as private key encryption) uses a single key for both encryption and decryption of the message.

What is the difference between handshake and change-cipher protocol in SSL?

Unless Handshake Protocol is completed, the SSL record Output will be in a pending state. After handshake protocol, the Pending state is converted into the current state. Change-cipher protocol consists of a single message which is 1 byte in length and can have only one value.
