Foundations of Cryptography

Cryptography has been employed for keeping secrets since the time of Caesar. From the simplest ciphers of shifting letters, to mathematically provably secure ciphers of today, cryptography has progressed a long way. It also has widened to a number of uses and capabilities to fit an ever growing number of applications. Cryptography makes it possible to keep data secure over an insecure network. It also makes it possible to keep private data on your computer safe from prying eyes. Even car thieves can be foiled by crypto systems in your remote unlock system.
