Am trying to understand the phase where the symmetric key is getting generating. From what I am understanding Diffie-Hellman is used to derive the symmetric key in TLS1.3
I am reading this tls explanation and so many keys are derived
Is th… Continue reading symmetric key generation in TLS 1.3
I am learning TLS handshake and find client/serve will negotiate a cihpersuite during client/server hello.
Usually, the last part of a ciphersuite is a hash algorithm, like SHA256 in ECDHE-ECDSA-AES128-SHA256. The second part of a ciphersu… Continue reading What is the relation between "signature_algorithms" handshake extension and TLS ciphersuite
I am working on implementing an Android App (client) which will be connected to Raspberry Pi (server) via Bluetooth Classic.
To make data transfer securely, I want to implement SSL encryption between client and server.
I have created the B… Continue reading SSL Handshake in Android via Bluetooth Classic
I have an embedded IOT device connected to real time DB FireBase. However, the server cancel the TLS handshake with fatal alert 0x46 = protocol_version. I have managed to get an hex dump of the whole handshake process.
Can someone explain … Continue reading TLS handshake failure [migrated]
I recently found out, that according to the RFC, SSH can negotiate two different cipher (and MAC) algorithms for server-to-client-encryption and for client-to-server-encryption (check section 7.1. for reference).
In section 6.3 this is als… Continue reading Why can SSH negotiatie two different encryption and authentication algorithms?
Networking newbie here.
I am running some experiments on IoT devices for which I need to capture the handshakes of the devices on my network in order to decrypt the frames I obtain through monitor mode. So far, I have been capturing the ha… Continue reading Automating handshake capture to decrypt 802.11 frames
Knowing how WiFi networks can be attacked is a big part of properly securing them, and the best way to learn about it is to (legally) run some attacks. [Matt Agius] has been going down the WiFi-cracking rabbit hole, and in the process created Pwnagotchi Tools to automate the actual …read more

I have read that the private key that the certificate owner/web server has (which is the corresponding private key of the public key presented on the certificate) is used to decrypt the data that the client sends to the server.
My question… Continue reading Priate key vs encryption session keys: For what is the private key used when there are session keys for encryption? [duplicate]
I am performing a MITM attack against my own network using bettercap and https proxy.
On my client-side I use the Google Chrome browser and navigate to https://webs.com
At the same time I use a script that analyzes client-side TLS security… Continue reading Strong TLS parameters even though MITM is being performed
