Introduction
Almost everything we do in the modern age is communicated digitally, and ensuring the security and privacy of these communications is very important. Secure messaging is the foundation of technical privacy. Cryptographic protocols such as Transport Layer Security (TLS) (TLS 1.0 (Dierks & Allen, 1999), TLS 1.1 (Dierks & Rescorla, 2006), TLS 1.2 (Dierks & Rescorla, 2008), TLS 1.3 (Rescorla, E. (2018))) and Secure Shell (SSH) (Ylonen & Lonvick, 2006) have emerged as the backbone for the security and privacy of data transmission. TLS is widely used for secure internet communications, while SSH is used for secure remote access and file transfers.
These protocols were not designed originally to handle today's privacy and security challenges. This blog post delves into the privacy implications associated with TLS and SSH. It also reviews real-world examples to help get a deeper understanding of the consequences of privacy issues in frameworks.

Privacy Issues in TLS
Transport Layer Security (TLS) is a cryptographic protocol that provides communication security and privacy over the Internet for applications such as web browsing, email, instant messaging (IM) and some virtual private networks (VPNs). TLS encrypts the data in transit between two endpoints, such as a web browser and a web server, or a client and a server. However, there are some privacy implications that should be considered when using TLS.
