TLSfingerprinting
TLS fingerprinting is a technique for identifying clients or devices by analyzing the patterns in their Transport Layer Security (TLS) handshakes as they appear on the network. By observing the initial messages exchanged during a TLS handshake, researchers can infer characteristics about the client without accessing its content.
The most common approach focuses on the ClientHello and, separately, the ServerHello. Fields such as the protocol
TLS fingerprinting serves multiple purposes. In security and network operations, it helps detect automated tools, distinguish
Limitations and concerns include the evolving nature of TLS, widespread use of TLS 1.3 and related privacy
