## What it is
Camo is an HTTP image proxy that routes insecure HTTP images through SSL to prevent mixed-content warnings on HTTPS pages. It authenticates proxy URLs with HMAC digests using a shared secret and supports size limits, redirect following, and content-type whitelisting.

## Use cases
- serve http images over https without mixed content warnings
- proxy user-submitted images through ssl
- prevent sidejacking of image assets on secure pages
- rewrite img src attributes in markdown to secure proxy urls
- self-host an ssl asset proxy for a website

## When to choose
- your site serves user-embedded images over https and you need to avoid mixed-content warnings
- you want an hmac-authenticated image proxy with cache busting and rate limiting hooks
- you need a battle-tested proxy like the one GitHub uses

## When to avoid
- you need a general-purpose http proxy rather than an image-specific one
- you want actively developed software with modern node support
- you need to proxy non-image assets like scripts or stylesheets

## Facets
- artifact type: service
- maturity: maintenance
- function: proxy, security, http-server, caching
- domain: web-development, security, privacy
- platform: self-hosted
