The term ‘Cryptography’ is derived from the Greek word ‘Kryptos’. Kryptos is used to describe anything that is hidden, obscured, veiled, secret or mysterious. In the world of data communications, cryptography can be defined as follows:
Cryptography, defined as “the science and study of secret writing concerns the ways in which communications and data can be encoded to prevent disclosure of their contents through eavesdropping or message interception, using codes, ciphers and other methods, so that only certain people can see the real message”.
Encrypting is the act of translating a ‘normal message’ to a message written with ‘secret characters’ (also known as the encrypted message). Decrypting is the act of translating a message written with ‘secret characters’ into a readable message (the unencrypted message). It is, by far, one of the most important areas in computer security, since modern encryption algorithms can ensure all three pillars of a secure conversation: privacy, integrity, and authentication.

Great introduction ! In short you have explained the meaning of cryptography which is simple and easy to understand for a layman. But its a very complex and vast concept which is highly interesting.
