Testing TLS/SSL encryption anywhere on any port
Role in this project:
Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:33 releases, 30 reviews, 3525 commits in 8 years 8 months
Contributions summary:Dirk's commits primarily focused on completing and enhancing the logic for the `$PROTOS_OFFERED` function, which is crucial for determining supported SSL/TLS protocols. Their work involved significant changes to the `testssl.sh` script, including modifications to the core functions used for testing SSL/TLS protocols and cipher suites, and ensuring proper handling of different connection problems in STARTTLS scenarios. The contributions indicate a focus on improving the script's robustness and accuracy in identifying vulnerabilities related to SSL/TLS, particularly regarding the detection of connection issues that may stem from either the server's protocol support or potential MITM attacks.
