How does TLS or SSL Decryption work ?

              Would you like to know how does TLS or SSL decryption work? Would you be also interested in knowing Symmetric and Asymmetric cryptography? If so, then you reached the right place. In this article, we will explore decryption with TLS or SSL. Let's start.

A) What TLS or SSL? 

               As discussed in what is the difference between HTTPS, SSL, and TLS  ? article, TLS or SSL is a cryptographic protocol for achieving privacy, data integrity over the network.

B) How does TLS/SSL decryption work? 

               The TLS and SSL both use asymmetric cryptography. TLS /SSL provides reliable security with high performance.

                a) Symmetric Cryptography :

                     Symmetric cryptography uses a secret key to encrypt data. The generated secret key is shared with the sender and receiver. The secret key should be 128 bits in length in order to achieve security.

                 b) Asymmetric Cryptography :

                      Asymmetric cryptography uses private and public keys. The public and private keys are mathematically designed. It requires higher bandwidth. The key length should be a minimum of 1024 bits.

                c) Secure session key : 

                     The secure session key is generated by SSL /TLS by using asymmetric cryptography. The secure session key is used to decrypt and encrypt the data transmitted over the network. secure session the TLS handshake is achieved with the secure session key.

C) What TLS handshake? 

               The TLS handshake is a process to achieve communication between server and client to achieve the below Functionalities -

               1. Acknowledge one another 

               2. Verify each other's authenticity 

               3. Designate encryption algorithms 

               4. Agree on session keys.
