Consider the following example –Size of Plaintext – 48 bytes.Size of MAC – 20 bytes.Block Length – 8 bytes.How many bytes of padding need to be added to the system?

Transport Layer Security (TLS) is a cryptographic protocol that protects data integrity and privacy for internet communications. It's used to encrypt communication between web applications and servers, such as when a web browser loads a website. TLS can also be used to encrypt other communications such as email and messaging.  TLS uses a combination of symmetric and asymmetric cryptography to establish an encrypted bidirectional data tunnel. When a server and client communicate using TLS, the server must provide a valid digital certificate to confirm its identity.  TLS is used in many... Show more

Transport Layer Security (TLS) is a cryptographic protocol that protects data integrity and privacy for internet communications. It's used to encrypt communication between web applications and servers, such as when a web browser loads a website. TLS can also be used to encrypt other communications such as email and messaging. 

TLS uses a combination of symmetric and asymmetric cryptography to establish an encrypted bidirectional data tunnel. When a server and client communicate using TLS, the server must provide a valid digital certificate to confirm its identity. 

TLS is used in many applications, including:
Secure web browsing
Email
File transfers
Video/audio conferencing
Instant messaging
Voice-over-Internet Protocol
Domain Name System (DNS)
Network Time Protocol (NTP) 

TLS was previously known as Secure Sockets Layer (SSL). Both TLS and SSL are client/server protocols that use cryptographic protocols to ensure communication privacy. All modern browsers support the TLS protocol.
