go-proxy

Simple implementation of a HTTP forwarding proxy.

Usage

Create a CA for the proxy. This creates a private key proxy-ca.key and a corresponding certificate proxy-ca.crt. These will be used to sign the certificates for the TLS interception.

go-proxy -create-ca

Run the proxy:

go-proxy

The proxy will listen under 0.0.0.0:8080.

Clients

To make HTTP requests over the proxy you have to configure your HTTP clients that they:

• Use the proxy
• Trust the CA of the proxy (proxy-ca.crt)

curl

curl --cacert proxy-ca.crt --proxy http://localhost:8080 https://example.com

Chromium

chromium --proxy-server=http://localhost:8080

Add the CA certificate of the proxy to the trust store. Go to Settings -> Privacy and security -> Security -> Manage certificates or just type chrome://settings/certificates in the address bar. Then click Import and select the proxy-ca.crt file.
