## Description

testssl.sh is a network security tool and SSL/TLS security scanner used to audit server configurations. It functions as a diagnostic utility that validates supported ciphers and protocols to identify cryptographic vulnerabilities and flaws in encrypted communication.

The tool is available as both a command-line utility and a dockerized security scanner, allowing for execution in isolated environments without the need for local dependency installation. 

Its capabilities cover SSL configuration auditing and TLS server security analysis. The system exports scan results into structured reports available in HTML, JSON, and CSV formats for security audits and compliance documentation.
