What is the method/type used for the point to point vpn tunnel encryption and what is the bit level for the data encryption?
I am concerned about how secure the connection and the data between the two points are.
Thanks

Every single IP packet is encrypted by AES 128 and authenticated by SHA1-HMAC. It is pretty much like IPsec.

However there is no way to confirm this because of the closed source aspect of your program. Hamachi has been confirmed to be secure by www.grc.com and Steve Gibson, Do you think you can contact him and let him know to review your software?

If have chance, we definitely like to let Steve Gibson to review our software. Any one knows how to contact him?

There might be a conflict of interests here : Steve Gibson has trumpetted (to his fan-audience) his next great project shall be a VPN solution with built-in cryptography and easy end to end autoconnection not unlike GBridge does IIUC. One difference is that "cryptolink" will surely not be free or even cheap !
Another difference is that, of course, cryptolink does not exist yet ;=)
However, S. Gibson reportedly filled a bunch of patents to cover for the not-yet-existing cryptolink technolgy.

I'm not questioning M. Gibson's integrity, but IMHO the above facts - easily verifiable on his nntp news group - would make it delicate for him to be an impartial expert on this system's.
