One of the ways that you can protect your assets and those you are responsible for is through encryption. Ever since the dawn of time, humans have developed systems to keep data secret so that only the intended persons had the information that they needed. The ancient Egyptians Developed Hieroglyphics with that in mind. Without the Key, you could not understand what was being transcribed on the walls of the city or in caves. Later at the height of the Roman Empire the Cesar Cipher was invented, it was a primitive form of cryptography (the science of encoding or making secret information so that only the intended parties can access it). The Cesar Cipher was based on a form of substitution, it was comprised of some letters substituted for the others. In Medieval Times Popes or Bishops had signet rings that they used to seal official church documents. The rings were considered very valuable as they attested to the authenticity or integrity of the documents that were being presented. Such was the case that when a Pope or Bishop died they rings were immediately ordered to be destroyed.
What is Cryptography?
Cryptography is the science of keeping data secret through technology, techniques and tools. Typically, cryptographers have a strong background in mathematics/physics and work for the government or big technology companies that specialize in security solutions. Encoding data or using cryptography is so important that many companies sell products to do just that. Universities also have researchers constantly investigating new ways to make information secret. With all of the technological advances, there are easier ways for intruders to steal your information, your money and cause you stress. The good new is, encrypting your hard drive is free. Most of the operating systems if not all of them offer hard drive encryption. If this is new to you, make sure you have a backup of your data before you start encrypting your hard drives. You should always have a backup
