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.

As some of you may know, I like technology, so I tend to play around with it a lot. One of my favorite ‘playtime’ activities is to completely rebuild one of the many sites I administer; and rebuilding my blog is always the most fun.

This being the case, my blog has always been run on one flavor or another of CMS (Content Management System).
