We’re sharing how we enabled third-party interoperability (interop) while maintaining end-to-end encryption (E2EE) and other privacy guarantees in our services as far as possible. WhatsApp and Messenger both use the tried and tested Signal protocol as a foundational piece for their encryption.

It’s interesting to observe how encryption and network performance monitoring (NPM) have evolved over time. Once you saw a person’s password to any given application, you knew they were generally using the same one for all of their other applications — email, the ticketing system, the FTP and Novell servers, etc.

In the future, significant advances in quantum computing will make it possible for adversaries to decrypt stored data that was encrypted using today’s cryptosystems. This is close to the typical TCP/IPv6 maximum segment size (MSS) of 1440 bytes, but is still fine for a full TLS handshake.

Understanding TCP ports is essential for managing network traffic and ensuring effective communication. But what is a TCP port? This blog will delve into what a TCP port is, how it works, its significance in networking, and the different types of ports, including well-known and dynamic ports. What is a TCP Port?

Websockets operate over a single, persistent TCP connection established between a client and server. If you were building a chat application prior to WebSockets, you would likely have your client-side app poll the server every n seconds to see if there are new messages to be displayed.

Source port for UDP or TCP, 0 for other protocols. Destination port for UDP or TCP, type and code for ICMP, or 0 for other protocols. If you are thinking that those represent HTTP and HTTPS, you would be largely correct, but that doesn’t mean it’s traffic involving web servers. Source IP address. Destination IP address.

A recap of QUIC and HTTP/3 QUIC is a secure-by-default transport protocol that provides performance advantages compared to TCP and TLS via a more efficient handshake, along with stream multiplexing that provides head-of-line blocking avoidance. Server receives the request HEADERS frame and validates it against RFC 9114 rules.
