Remember the days when passwords to the treasures were accessible by easy-to-remember sayings like, "Open, Sesame" ? It was all so simple then. While some users might have passwords even more obvious than that (Note: One of the more popular passwords of 2011  was simply "password"), the need for password sophistication and security has multiplied in the modern era, as data and information have become intrinsic parts of our lives.
Today, we use passwords to access everything from e-mail to bank accounts. But the people of the 21st century aren't the only civilization that realized the need for security and data protection.

Check out the infographic on the history of encryption below.
