camo - 2.3.0+dfsg-1.1 main

Camo is an image proxy to prevent mixed content warnings on secure
pages.
.
It should not be installed by an end-user; instead people who operate
websites that allow user-specified image embeds by URL can run this as
a daemon to proxy such images through their own servers and serve the
resulting content over SSL/TLS.
.
This provides integrity protection and last-mile confidentiality to
images, thus preventing a local network attacker from seeing the images
you request (allowing for possible disclosure of the content you're
viewing) or changing their content (to misinform, confuse, or shock).
.
It of course does not prevent an attacker from modifying the content or
noticing its access if the attacker is in the path between your
datacentre and the image source.
.
However, even in this case, it provides some security insofar as it
may prevent the attacker from knowing who is accessing the image.
.
Using a shared key, proxy URLs are encrypted with hmac so we can bust
caches/ban/rate limit if needed.
.
Features include:
* Proxy Google charts
* Proxy images under 5 MB
* Follow redirects to a configurable depth
