Nogotofail

Nogotofail is a network security testing tool designed to help developers and security researchers spot and fix weak TLS/SLL connections and sensitive cleartext traffic on devices and applications in a flexible, scalable, powerful way. It includes testing for common SSL certificate verification issues, HTTPS and TLS/SSL library bugs, SSL and STARTTLS stripping issues, cleartest issues and more.

Nogotofail is composed of an on-path network MiTM and optional clients for the devies being tested. The MiTM is designed to work on Linux machines and the transparent traffic capture modes are Linux specific, which require iptables as well.
