Why this tool?
Tlsenum is a CLI tool to enumerate TLS protocol and TLS cipher support by a server. The tool lists then the output based on the order of priority. Tlsenum can be used to find the supported protocols and ciphers of a system and determine if it is properly hardened. This information can be useful to system administrators and pentesters doing a security assessment of the system.
How it works
This tool works by sending out sending out TLS ClientHello messages. Any ServerHello responses from the server are parsed. It assumes that the server is the one which decides the preferred cipher suite, giving an idea on the available ciphers.
Usage and audience
tlsenum is commonly used for information gathering, security assessment, system enumeration, or system hardening. Target users for this tool are pentesters and security professionals.
