How does SSL work step by step?

In this article, we will go over the process of how an SSL (Secure Socket Layer) works. What is an SSL connection? SSL (Secure Sockets Layer) is a security protocol that has become mandatory for secure communication over the Internet. Before SSL, people could use unsecured networks, such as the Usenet.

When a connection uses SSL, the following steps are performed: Server -> Client (Step 1). (Step 1) Client -> Server (Step 2). (Step 2) Server -> Client (Step 3). The first step is completed in this diagram. In it, the server has a session key and public key that can be used by the client. The public key is sent from the server to the client via the network, allowing the client to identify the public key of the server.

Then the client sends the data it wants to send to the server, and the server responds to the client with a confirmation that the message is accepted and that the server received the data that was sent by the client. If the user wants to read or write data to the server, it is encrypted and the server responds with an encrypted copy of the data. This is done by using the session key that the server and the client share.

The last step, is the confirmation by the client to the server that it has successfully received the data from the server. This happens when the server sends an encrypted confirmation to the client. The client checks that the response from the server matches the data that was sent from the server to the client. If the response matches, then the client assumes that the data was not tampered with and the session is considered open.

What is TLS encryption and how does it work?

In this article, we are going to take a look at the concept of the Transport Layer Security (TLS) protocol. The name of the protocol itself is actually a little misleading and comes from the fact that it's supposed to be added at the transport layer so the connection layer. On the web, for example, your computer, smartphone or tablet connects to an IP server (Internet Protocol) and can fetch content (usually web pages). All content transfer through the internet are sent over TCP (Transport Control Protocol) and TLS is added to secure the traffic in between. But let's take a look at the core principle behind TLS and how it works first.

TLS connection basics. Before we dive deep into TLS encryption protocols and how the whole thing works, let's take a quick look at the concept of the Internet in general and how TCP is currently used to ensure the transfer of data between computers over a connection to the network. Before we explain the basics of SSL/TLS connections using the common Internet Protocol (IP), let's take a look at the general protocol which makes it all possible.

The Internet protocol (IP) was designed with the intention of ensuring communication over the intercontinental network. A message is sent by someone one computer or smartphone to someone on another location across the world. It's always important that an encrypted connection is established first. You need a common encryption algorithm like AES (Advanced Encryption Standard) and a key used to encrypt and decrypt the traffic. There is also a checksum used to avoid any accidental damage and incorrect messages can easily be detected by a special checksum. Once the protocol has been established and the message has been sent, the sender ends the communication that's where the basic logic is for Internet communication. If it's encrypted properly, there won't be any way to know who the original sender was, even for the original recipient.

What is Transport Layer Security? The way it is implemented is similar to the IP protocol for example, most commonly used, TCP (Transmission Control Protocol). The concept of how the connection should work is roughly the same. You will need to establish a connection over a reliable transport protocol to establish a connection between two devices that want to communicate.

How does TLS works step by step?

When a person accesses your website, the person will pass through several certificates issued by TLS Certificates Authority (CA). How does the CA issue the TLS certificates? How to issue TLS certificates? Please explain from this point step by step.

Thank you for your help! The initial communication is done using unencrypted HTTP (ie http) connection. During this initial communication there is a handshake. The server sends a certificate message to the client and the client sends back a certificate message containing the public key and an agreement on the use of some cipher suite.

The purpose of this exchange is to assure that the server has signed its certificate. In other words, it proves that the certificate has not been altered during transmission.

Certificates are signed with a private key. The public key of the certificate is used during the handshake in order to authenticate the client and verify the signature of the certificate.

In order to authenticate the certificate, the certificate authorities (CAs) have to sign the certificate themselves. Thus, it is important that they have been able to confirm their private key, which is not a trivial task.

After the handshake, TLS is negotiated. The handshake uses the same cipher suites as the subsequent communications. The cipher suites determine the cryptographic primitives and the strength of the security proof associated with each protocol. For instance, RSA-SHA-256 is weaker than elliptic curve signatures.

Once the TLS protocol is negotiated, the connection is encrypted with a public key and the symmetric encryption with a secret key (asymmetric encryption). The communication after this point is protected by the encryption and authentication mechanisms of TLS.

How does the TLS app work?

IOS has recently updated TLS in their app and it's very useful to have.

I would like to understand how it works.

What happens when you're browsing the Internet with it enabled? Are all of the TLS connections between all apps and your Apple TV encrypted (even if it's just for logging into a site) or is it all encrypted to the point where a government (in this case the USA) cannot read the data in your traffic? Does Apple TV use a key that they provide to all apps and websites that have implemented the TLS protocol? What key is used? The Apple Key maybe? Does the Apple key work on all iOS devices and the Apple TV? Is Apple providing this key for any purpose other than encryption or security? TLS provides end-to-end protection of the stream, including transport security, authentication and encryption. That is, the transport can be completely private between client and server, the connection can be protected from malicious man-in-the-middle attacks, and the data can be kept secret.

All HTTPS requests and responses between an iOS device and the server are already using TLS to protect the connection. But the server is unaware that anything else is going on. So Apple TV does not provide any end-to-end security for anything else going on besides HTTPS requests.
