What it is
With Hamachi you can organize two or more computers with an Internet connection into their own virtual network for direct secure communication.

Hamachi is fast, secure and simple. It is also free.

What's in it for me
Think - LAN over the Internet.

Think - Zero-configuration VPN.

Think - Secure peer-to-peer.

Access computers remotely. Use Windows File Sharing. Play LAN games. Run private Web or FTP servers. Communicate directly. Stay connected.

Technology
Hamachi is a zero-configuration virtual private networking application with an open security architecture and NAT-to-NAT traversal capabilities.

Hamachi is the first application to mix seemingly unrelated networking technologies in one powerful package to deliver an unprecedented level of peer-to-peer connectivity. More ...

Security
Hamachi is secure. All Hamachi communications are encrypted and authenticated with industry-standard algorithms and protocols. Nobody will be able to see what two Hamachi peers are talking about. Not even us.

However what is equally important - Hamachi security architecture is completely open meaning that its detailed description is available for the review to anyone interested. More ...

Ease of Use
A special effort went into designing and polishing Hamachi user interface. The result is sleek, simple and intuitive, while still very much functional. Everything you need, nothing you don't.

Hamachi software contains no spyware, bannerware or any other -ware unrelated to its purpose. And it never will.

0.9.9.8 is out.

The main change is of course the conversion of the entire package
to Unicode, which allows now to translate all textual information into
virtually any language. For the list of currently supported translations
please vist Downloads page.

IPX support has been restored into a working state from being partially
broken since 0.9.9.3 release.

Installer now has fancy looking 'Loading' splash screen. It also uses
a better compression, so the package size went down by another
50K eventhough it now contains extra 20K of text in a language file.

Special note for those who installed RC versions
You will have to manually update RC version to an official release
by downloading the package from the Downloads page. Failure to
do so may cause you some non-fatal, but nevertheless pretty
unpleasant problems.
