SSL Cipher Checker

The tool analyzes a target server's TLS configuration by performing a TLS handshake to enumerate supported cipher suites and protocol versions. It reports which ciphers are accepted, which provide forward secrecy, and whether TLS 1.3 is in use. It also identifies weak or deprecated options such as legacy CBC or non-AEAD ciphers and ranks overall security posture. The core objective is to help operators verify that a host rejects weak ciphers and prefers modern TLS versions. Core features include real-time handshake-based cipher discovery, protocol version detection, strong/weak cipher classification, and a security grade with actionable recommendations. The tool supports both standard and advanced modes, allowing testing of custom or restricted ciphers when needed. Outputs are presented in structured data for automation and in human-readable summaries for analysts. Use cases include pre-deployment hardening, routine security audits, and compliance validation. Unique value comes from a precise handshake-based assessment that mirrors real-world client behavior and from prescriptive hardening guidance tailored to TLS configuration.
