![]() ![]() Some people prefer to differentiate the words, using cryptology to refer to the science and cryptography to refer to the practice of secret writing.Ī cryptographer would write the letter "B" as "12". You Say Cryptology, I Say CryptographyIn English, the words cryptology and cryptography are often interchangeable - both refer to the science of secret writing. Today, even the amazingly complex encryption schemes common in Internet transactions may have a limited useful lifetime - quantum computing might make solving such difficult equations a snap. Cryptanalysts have proven these people wrong by relying on everything from the scientific method to a lucky guess. ![]() Throughout the history of cryptography, people who created codes or ciphers were often convinced their systems were unbreakable. What cryptographers create, cryptanalysts attempt to unravel. Cryptographers might use codes, ciphers or a combination of both to keep messages safe from others. These people are cryptanalysts, also known as code breakers.īinary code is the basis for many modern ciphers.Ī person who communicates through secret writing is called a cryptographer. On the other side of the information equation are people who use a combination of logic and intuition to uncover secret information. ![]() Nations, corporations and individuals protect secret information with encryption, using a variety of methods ranging from substituting one letter for another to using a complex algorithm to encrypt a message. This closeup shows some writings from the notebook of Enigma codebreaker Alan Turing, who played a major part in breaking codes during the Second World War. ![]()
