GitHub - WestpointLtd/tls_prober: A tool to fingerprint SSL/TLS servers
TLS Prober is a tool for identifying the implementation in use by SSL/TLS servers. It analyses the behaviour of a server by sending a range of probes then comparing the responses with a database of known signatures. Key features include: Requires no knowledge of the server configuration. Does not rely on the supported cipher suites (since administrators often change those). Successfully identifies
