«Cryptography is the study of secure
communications techniques that allow only
the sender and intended recipient of a
message to view its contents. The term is
derived from the Greek word kryptos,

which means hidden. It is closely
associated to encryption, which is the act
of scrambling ordinary text into what's
known as ciphertext and then back again
upon arrival. In addition, cryptography also

covers the obfuscation of information in
images using techniques such as microdots
or merging. Ancient Egyptians were known
to use these methods in complex
hieroglyphics, and Roman Emperor Julius
Caesar is credited with using one of the

first modern ciphers.»
