The README document contains some very good reasons to use this software.
But here we must give you some reasons not to...
TECHNICAL RISKS
The Grapevine's architecture is such that it downloads its "firmware" from the
web, and if it passes a signature test, it runs it in a sandboxed environment.
This allows us to use the real network as a development platform, but it does
entail some risk to you.
Please be aware of the following risks:
* This software authorizes us to put new code onto your system on an
on-going basis. Such code is restricted by the sandboxing rules.
Remember that whenever you install software onto your system, you are
forced to trust the author of that software.
* The sandboxing prevents access to the files on your system, but it does
not restrict network access. This means it could cause your machine to
generate malicious network traffic for which you might be blamed.
* Our encryption keys could potentially be stolen, so malicious code could be
introduced that way.
* The sandboxing means that the code cannot read or write any information to
your disk, apart from reading software from a certain directory, and
reading/writing a single file called 'grapevine.dbm'. Malicious code
could, however, fill this file up with junk and give you a full disk.
* While we have been careful in implementing this code, the sandboxing could
potentially have faults. This means that there exists a remote possibility
that malicious Grapevine firmware could introduce a virus onto your system.
* The Grapevine is a peer-to-peer network. This means that the nodes on the
network collectively contain enough information to reach all computers
that are part of the grapevine network. This in itself is a risk, because
this information could be used by an Internet worm in a similar way to the
way in which email viruses use the victim's email address book. Such a
worm cannot exist unless there is an exploitable security hole in your
system. Unless you are on a security mailing list and patch your system
when necessary, you are at risk.
If you are helping us test, then please consider joining the
grapevine-announce mailing list.
LEGAL RISKS
Disclaimer: I Am Not A Lawyer
The Grapevine protects you from accusations of information crimes by
encrypting the data it stores on your disk. The software cannot prevent
someone proving that a certain part of a certain file was sent from, or was
stored on your machine (though it does make it as difficult as possible).
However, you can truthfully and plausibly argue that you did not know it was
there. This principle is called "plausible deniability", and it may or may
not protect you legally.
In many countries, you are legally required to hand all your encryption keys
to the authorities on demand. The Grapevine does not make these keys
available to you, so it becomes impossible for you to comply. In many
countries (the United Kingdom included) this is no defence, and you can be
prosecuted.
** THE USE OF THIS SOFTWARE MAY BE ILLEGAL IN YOUR COUNTRY. YOU HAVE BEEN
WARNED. **
We sincerely hope that we have proven our honesty rather than put you off, and
that you will give us the help we need to make this project a success.
Please type "yes" if you have understood these risks and you want to install
the Grapevine Project software.
