Cryptography - definition(s)

Cryptography - Literally, the word means the art of secret writing.   It means the conversion of writing into a form that cannot be understood without specific knowledge.   (Cryptography started long before computers, with the ancient Egyptians. Computers have simply helped to automate the processes.)   Cryptography is not the only method you can use to communicate information secretly.   Steganography is a technique for hiding information inside other information (a picture with a person wearing a hat has one meaning, and the same picture with the person not wearing a hat has a different meaning).
