Borxy version: Broxy v1.0.0-alpha.3

The CA Cert in the coreproxy_settings.go file is static and not something that gets generated. Anyone who trusts the Cert in order to capture HTTPS traffic will be vulnerable to using unverified sites later.

Example site signed with the hardcoded CA https://proxy.lf.lc/

Hey! So I love this project and it's something I've been toying with building myself. I'd love to help in anyway I can like taking a feature off your hands to build. I've built a handful of Go tools which you can see on my github for some reference. Let me know if you'd like the support!

I'm getting lots of cert errors. I've saved the CA from within broxy and imported it into firefox.

Example error: 2020/07/04 14:07:20 [095] WARN: Cannot handshake client github.githubassets.com:443 EOF 2020/07/04 14:07:20 [081] WARN: Cannot write TLS response header from mitm'd client: write tcp 127.0.0.1:8080->127.0.0.1:44238: write: broken pipe

If we could disable the automatic update of the Content-Length header, this tool would be usable to test for HTTP Smuggling attacks: https://portswigger.net/web-security/request-smuggling

I am not very good at programming on golang yet, and I would like to contribute in some way to the project such as giving ideas or possible improvements and reporting errors. If possible, you could provide information to help with software development.

to fix:

• fix request/response format

ex: curl -k https://www.google.cl -x http://127.0.0.1:8080

Request:

GET /www.google.cl:443/ HTTP/1.1
Host: www.google.cl
User-Agent: curl/7.58.0
Accept: */*

Correct request:

GET / HTTP/1.1
Host: www.google.cl:443
User-Agent: curl/7.58.0
Accept: */*

• use unicode

The possible improvements that can be added in the short term would be in my opinion:

• Copy as curl, python-requests https://github.com/hrbrmstr/curlconverter
• Add scope or option to remove junk traffic from the browser, for example firefox.
• In the proxy and repeater history, detail the response timeout.
• Add highlight to differentiate one request from another.
• The request and response of the broxy do it with letter console. (more comfortable to read)
• Decoder:     - urlencoder / urldecoder     - base64 encoder / decoder
• Comparer

Less important:

• Export proxy history to csv, json, xml or pcap.
• add highlight to the request and response.
• add a crawler. https://github.com/PuerkitoBio/gocrawl.
• have a history of requests made by the complete tool as logger++
• Fuzzer (intruder) is not necessary something advanced, just to be able to put dictionaries and perform the attack is great // https://github.com/ffuf/ffuf // https://github.com/xmendez/wfuzz
