Certigo examines and validates certificates, helping debug SSL/TLS issues. The project enables users to examine certificates in formats like X.509, JCEKS, PKCS7, and PKCS12. It also connects to remote servers to validate certificate chains and identify potential errors, such as outdated X.509 formats or weak signatures. Certigo primarily uses Go for its implementation and leverages standard Go libraries for network and data processing.
Certigo's key strengths are its comprehensive format support, including automatic detection, and its powerful scripting capabilities through JSON output. Its ability to connect to remote servers and perform validation makes it well-suited for automation and troubleshooting. The CLI design allows for flexible usage with various options for filtering and formatting results.
- Format Support: Handles X.509, JCEKS, PKCS7, and PKCS12 certificates.
- Remote Validation: Connects to servers and validates certificate chains.
- Scripting Output: Supports JSON output for integration with shell scripts.
- StartTLS Support: Enables connections via StartTLS protocols for various services.
- CLI Flexibility: Offers various flags and options for customizing analysis and reporting.
Certigo is an active project with regular updates and recent commits, indicating ongoing maintenance. Documentation is comprehensive, including detailed command-line usage and examples. The project has a solid community presence, evidenced by its star count and active issue tracking, suggesting a reliable and well-supported tool.
Certigo benefits developers, system administrators, and security professionals needing to examine, validate, and automate certificate analysis tasks. It addresses scenarios like troubleshooting SSL/TLS connections, verifying certificate chains, and integrating certificate validation into automated workflows. It offers a robust alternative to manual certificate inspection and scripting with other tools.
