mitmproxy/README.mkd

mitmproxy is an SSL-capable, intercepting HTTP proxy. It provides a console interface that allows traffic flows to be inspected and edited on the fly.

mitmdump is the command-line version of mitmproxy, with the same functionality but without the frills. Think tcpdump for HTTP.

Both tools are fully documentented in the commandline --help flag, and, in the case of mitmproxy, a built-in help page accessible through the ? keyboard shortcut.

Capabilities

• Intercept HTTP requests and responses and modify them on the fly.
• Save complete HTTP conversations for later replay and analysis.
• Replay the client-side of an HTTP conversations.
• Replay HTTP responses of a previously recorded server.
• Make scripted changes to HTTP traffic using Python.
• SSL certificates for interception are generated on the fly.
