I am currently trying to learn the TCP session creating (3 way handshake) process in detail. I was wondering what the sequence number means and also why is the ack num for the next ACK packet always the sequence number of the previous pack… Continue reading What is sequence number and why is it used as the ACK number for the next ACK packet?

I was running MQTT broker in my pc and tried to connect to it via mqtt client in same PC. using x509 cert for mutual tls. SSL Handshake was failing with RST from server. This was happening only in my PC.
When I tried to do the same setup i… Continue reading SSL handshake failure | Client hello(success) -> Server ACK (success) -> server RST (connection closed)
What version of TLS would be required for a router that separates client requests from a web server behind a router?
Let’s say the supported TLS client is 1.2 and so is the web server, BUT the router doesn’t support TLS 1.2, it’s only 1.0…. Continue reading Web request TLS
I’ve been looking to find example .cap files to see how a wpa2 handshake really looks like in bytes. I couldn’t find off much from research. How big is a wpa2 handshake ? While bruteforce happens, how does the brute force tool do it really… Continue reading is wpa2 handshake outcome the same for same passwords?
I was experimenting with WireShark and TLS decryption of the traffic. Every guide I’ve found states that I need to capture the pre-master secret generated by the client and then configure WireShark to actively use it, in order to decrypt t… Continue reading Details about pre-master secret [duplicate]
I’m testing a new proxy and monitoring the connection using Wireshark, but I’m not seeing any certificate at all. my goal is to find out exactly what sensitive and identifiable data is leaving my router after using this proxy, emphasizing … Continue reading How can I view the TLS 1.2 and 1.3 certificates in Wireshark? [migrated]
I heard recently that WPA2 passwords can be brute forced if somebody captures handshake (which is not very difficult). Can somebody tell if a similar method exists for cracking SSH traffic? I mean some method for brute forcing my password … Continue reading Is brute force for SSH similar to cracking WPA2 handshake?
I am wondering about the different TLS records sent by the Client and Server. In TLS 1.2, there are 10 different Handshake Protocol types as defined here.
I implemented a TLS monitoring tool that lets me inspect different TLS packets/recor… Continue reading Can any Handshake Protocol message type sent by Server or Client? [closed]
Having some trouble communicating with our SharePoint Online (SPO) site.
I am simply going to a browser (IE v11) on a Windows Server 2012 R2 VM and navigating to the SPO home page.
In Wireshark I see this trace where <ip_SPO> is the … Continue reading TLS1.2 Handshake to SharePoint Online Failing from Windows Server 2012 R2
After looking at many explanations about the TLS handshake I noticed that sometimes the server starts with the change cipher spec command and sometimes the client starts with it.
I’m wondering why. Is it due to the type of key exchange pro… Continue reading Who starts with change cipher spec in a TLS handshake?
