Hello,

I've been reading about a protocol called TCPCrypt (http://tcpcrypt.org/index.php), it looks good. From what I can tell TCPCrypt only works if both the client and the server have TCPCrypt installed. Is this correct?

My question is, is TCPCrypt widely used? Is it worth installing and trying? If it isn't widely used then it wouldn't encrypt much. I ask because this is the first I've heard of TCPCrypt, and google isn't telling me much about TCPCrypt being widely used.

I know VPNs and encrypted proxies/SSH are an effective way to encrypt traffic, I'm curious and trying to learn about various ways.

If you read the information on that website correctly, they specifically stated that TCPCrypt, must be installed on both ends or else it will fall back to the standard TCP/IP protocol and no communication will be encrypted. So yeah, before using it you must make sure the end system supports it.
