## What it is
sslstrip is a Python command-line tool that implements Moxie Marlinspike's SSL stripping man-in-the-middle attack, downgrading HTTPS links in intercepted HTTP traffic to plain HTTP. It works alongside ARP spoofing and iptables redirection to capture credentials and session data from victims on a local network.

## Use cases
- demonstrate ssl stripping attacks in security training
- test whether a network is vulnerable to mitm downgrade attacks
- capture credentials over http during a pentest
- learn how https downgrade attacks work
- audit client-side https enforcement on websites

## When to choose
- performing authorized penetration tests on local networks
- teaching or demonstrating TLS downgrade attack concepts
- auditing legacy sites that still serve http links

## When to avoid
- any use without explicit authorization from network owners
- modern environments with HSTS and HTTPS-everywhere defaults, where the attack is largely ineffective
- projects needing maintained tooling - it targets Python 2 and is unmaintained

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, networking, proxy, penetration-testing
- domain: security, penetration-testing, networking
- platform: python, cli
- tags: mitm, ssl-stripping, man-in-the-middle, arp-spoofing, pentest, linux
