Which encryption method is used for transport connection encryption?

• A. RSA 2048
• B. AES 256
• C. TLS
• D. Blowfish 56 bit

Answer: (C)

TLS, or Transport Layer Security, is the primary encryption method used for securing transport connections over networks. It is designed to provide privacy, integrity, and authenticity of transmitted data between applications or services, particularly over the internet. TLS works by establishing a secure channel between a client and a server, encrypting the data packets sent across this channel, which protects against eavesdropping and tampering.

The strength of TLS lies in its ability to provide a robust framework for encryption, which typically involves the use of asymmetric encryption for key exchange during the handshake process and symmetric encryption for the actual data transmission. Since it specifically caters to securing transport connections, it is widely adopted in various applications, including web browsing (HTTPS), email, messaging, and other forms of communication over insecure networks.

Other options presented, while they do have their own contexts in which they are useful, do not directly encompass the concept of transport connection encryption in the same way that TLS does. RSA 2048 is an asymmetric encryption algorithm primarily used for secure key exchange, AES 256 is a symmetric encryption algorithm that is often used within TLS but does not handle the entire transport security process, and Blowfish 56 bit, although it serves as an encryption method, is considered less secure by
