CryptoLyzer is a server cryptographic protocol analyzer that examines TLS, SSL, SSH, and DNSSEC implementations along with related security settings.
The tool provides comprehensive analysis capabilities for cryptographic protocols and can generate fingerprints including JA3 and HASSH tags for network traffic identification. It evaluates HTTP security headers and DNS records as part of its assessment functionality.
CryptoLyzer offers both API and command-line interfaces to accommodate different integration requirements. The CLI supports multiple output formats including colorized terminal output for manual analysis, machine-readable JSON for automated processing, and human-readable Markdown for documentation generation.
The tool utilizes a custom cryptographic protocol implementation called CryptoParser, designed to provide thorough analysis while maintaining a compact codebase. This approach enables detailed examination of server cryptographic configurations and protocol implementations.
