Cryptography is the science of writing in secret code for the motive of hiding information.

The first known use of cryptography in writing dates back to circa 1900 B.C. when an Egyptian scribe used non-standard hieroglyphs in an inscription. Few specialists argue that cryptography emerged soon after writing originated.

Earlier cryptography techniques only included microdots, merging words with images, and other ways to hide information in storage or transit. But in today’s computer-centric age, cryptography is time and again associated with scrambling plaintext into ciphertext, then back again.

Cryptography and security go hand in hand, as cryptography is purely used as a security method of storing and transporting data.

Cryptography is used in technically complex applications, such as security of ATM cards, computer passwords, and electronic business, which all depend on cryptography. In the United States, cryptography is legal for domestic use, but there has been much conflict over legal issues related to cryptography, export controls and civil liberties.
