BackTrack4

Well, it’s here… BackTrack4!  All pretty and packaged up, I have already burnt 2 copies (One for use the other for archive), and knowing that other security geeks will be doing the same I put together a BackTrack4 LightScribe Template (BackTrack4 Label), all pretty and packaged up.

Make sure you have the darkest settings on, in your LightScribe Labeler.

Public Key Cryptography

Overview

Symmetric ciphers use the same key for encryption and decryption, which creates a default insecurity due to Alice and Bob sharing the key knowledge. Technically, the true measure of security within a symmetrical cipher is to measure the security of the means by which the key is shared.  Compromised keys can result in an incredibly easy decryption and potentially further security issues. As an alternative, asymmetric cryptography utilizes two (mandatory) different keys, in an attempt to eliminate the key sharing insecurities.  These asymmetrical ciphers are found most commonly in Public Key Cryptography.
