WebNov 4, 2024 · Symmetric cryptography itself is a process that’s thought to have been created thousands of years ago. An early example of symmetric encryption — and probably the best-known symmetric cipher — is attributed to the Roman General Julius Caesar. This particular cipher is aptly known as the Caesar Cipher (more on that in a couple of minutes). WebIn 1500 BC, a Mesopotamian scribe used cryptography to conceal a formula for pottery glaze. This example is the first known use of cryptography to hide secret information. These aren’t the only examples, though. There has been evidence of use of cryptography in almost every major early civilization.
Although cryptography has a long and complex history, it wasn't until the 19th century that it developed anything more than ad hoc approaches to either encryption or cryptanalysis (the science of finding weaknesses in crypto systems). Examples of the latter include Charles Babbage's Crimean War era work on mathematical cryptanalysis of polyalphabetic ciphers, redeveloped and published somewhat later by the Prussian Friedrich Kasiski. Understanding of cryptography at th…
