third-wheel is a TLS man-in-the-middle proxy written in rust, with the aim of being lightweight and fast. It is currently in beta.
third-wheel is a library so you can modify it's behaviour in order to capture traffic, or modify it en route. It also comes with some examples; you'll need to have run set_up_and_validate_environment.sh first as to generate the root certificates. The simplest example, trivial_mitm, simply proxies the traffic but does not do anything to it, you can run with cargo run.
cargo run --example trivial_mitm -- --help
will give you some hints. If you just want a TLS mitm proxy:
cargo run --example trivial_mitm -- -p 8080
will get it running on port 8080.
To test you can run curl against it with
curl -x http://127.0.0.1:8080 https://google.com -vv --http1.1 --cacert ./ca/ca_certs/cert.pem -L
from the third-wheel directory.
For something more exciting, use har-capturer to record a har file of the session:
cargo run --example har-capture -- --help
If you want to develop/use third-wheel while still in early stages you will need to generate the certificate authority certificates and check your local version of curl and openssl are working as expected. Run the set_up_and_validate_environment.sh script to do this.
The test_against_chrome.sh and test_against_firefox.sh scripts uses Docker, (Chromium|Firefox) and Selenium to test that the browsers are tricked by the mitm. It does most of the setup for you but you do need docker installed for it to work. It uses sudo to run docker because it doesn't assume you've modified the docker group - if you have done so feel free to delete the sudo's and then feel more confident running the script :)
