HTTP tunnel. The HTTP stream with its covert channel is termed an HTTP tunnel.
HTTP tunnel software consists of client-server HTTP tunneling applications that integrate with existing application software, permitting them to be used in conditions of restricted network connectivity including firewalled networks, networks behind proxy servers, and network address translation. Usage Mechanism The mediater server unwraps the actual data before forwarding it to the remote host in question. Symmetrically, when it receives data from the remote host, it wraps it in the HTTP protocol before sending it as part of an HTTP response to the application. In this situation, the application plays the role of a tunneling client, while the remote host plays the role of the server being communicated with. HTTP CONNECT tunneling A variation of HTTP tunneling when behind an HTTP Proxy Server is to use the "CONNECT" HTTP method. HTTP tunneling without using CONNECT HTTP tunnel clients Geek to Live: Encrypt your web browsing session (with an SSH SOCKS proxy)
File Encryption Software - TopTenREVIEWS. Five Best File Encryption Tools. How cryptography is a key weapon in the fight against empire states. The original cypherpunks were mostly Californian libertarians.
I was from a different tradition but we all sought to protect individual freedom from state tyranny. Cryptography was our secret weapon. It has been forgotten how subversive this was. Cryptography was then the exclusive property of states, for use in their various wars. By writing our own software and disseminating it far and wide we liberated cryptography, democratised it and spread it through the frontiers of the new internet. The resulting crackdown, under various "arms trafficking" laws, failed. Our work in WikiLeaks imparts a keen understanding of the dynamics of the international order and the logic of empire. The struggle for Latin American self-determination is important for many more people than live in Latin America, because it shows the rest of the world that it can be done.

INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. What is a Digital Signature? Bob has been given two keys.

What is Visual Cryptography Visual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used.
The technique was proposed by Naor and Shamir in 1994. Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information.
