Etymology
The word 'cryptography' is a modern construction from ancient Greek components, entering English via scientific Latin. Its literal meaning, "hidden writing," is a direct and logical composite of its parts: kryptos (hidden) and -graphia (writing). This term was adopted in the 17th century to formally describe the practice of secret communication through coded messages, a concept that has existed for millennia. The evolution from its literal Greek roots to its modern, specialized meaning in computer security demonstrates how classical language provides precise terminology for advanced technological fields.
