Question about data encryptoin.

[Pattonias]

I was wondering if there is software that will encrypt the data on one end transmit it, then decrypt it on the other end without actually transmitting the key. The key would be held on the sending and receiving end without ever being transferred between the two. It would be manually installed on both computers and used to encrypt and decrypt without revealing the key over the network?

Perhaps this already occurs and I am unaware?

Just tryine to learn a little bit more.

Public key encryption might be what you're asking about. Here's a link to a wiki article - http://en.wikipedia.org/wiki/Public-key_cryptography.

Thank you very much, that was very helpful. I had tried searching myself, but found way too much information all at once.
