Stolen Camera Finder - find your photos, find your camera Email Security using Public Key Cryptography Introduction Anyone using Email that is concerned about the security of the data being transferred should use Public Key Encryption. There are several open source software tools like GnuPG and WinPt to accomplish these tasks. The primary benefit of public key cryptography is that it allows people who have no preexisting security arrangement to exchange messages securely. The need for sender and receiver to share secret keys via some secure channel is eliminated; all communications involve only public keys, and no private key is ever transmitted or shared. This Tip describes the installation and use of GnuPG and WinPt If you want to send an encrypted mail to somebody, you encrypt it using the public key. GnuPG ( GnuPG is a complete and free replacement for PGP. WinPt WinPT (Windoze Privacy Tray) is a taskbar utility for doing data en- or decryption. Configuration of GnuPG / WinPt Create the following entries in your registry (regedit) under the path: Usage
Cypherpunk A cypherpunk is any activist advocating widespread use of strong cryptography as a route to social and political change. Originally communicating through the Cypherpunks electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherpunks have been engaged in an active movement since the late 1980s. History Before the mailing list Until about the 1970s, cryptography was mainly practiced in secret by military or spy agencies. The technical roots of Cypherpunk ideas have been traced back to work by cryptographer David Chaum on topics such as anonymous digital cash and pseudonymous reputation systems, described in his paper Security without Identification: Transaction Systems to Make Big Brother Obsolete (1985). In the late 1980s, these ideas coalesced into something like a movement. Cypherpunk mailing list Early discussion of online privacy Main principles The term cypherpunk is mildly ambiguous.
'Uncrackable' codes set for step up 4 September 2013Last updated at 13:09 ET By Melissa Hogenboom Science reporter, BBC News Quantum cryptography is a way to share secret digital keys A system that allows electronic messages to be sent with complete secrecy could be on the verge of expanding beyond niche applications. A team of British scientists has discovered a way to build communications networks with quantum cryptography at a larger scale than ever before. Quantum cryptography has the potential to transform the way sensitive data is protected. Details appear in Nature journal. The system is based on a communication system, where information is carried by individual photons - single particles of light. Once these single photons of light are observed, they change.
