WebHistory of cryptology. There have been three well-defined phases in the history of cryptology. The first was the period of manual cryptography, starting with the origins of the subject … WebMar 8, 2024 · A major breakthrough in cryptography was described, though perhaps never built, by Thomas Jefferson in the 1790s. His invention, known as the cipher wheel, consisted of 36 rings of letters on moving wheels that could be used to achieve complex encoding.
