Define Cryptography?

Cryptography is a technique used to protect information from third parties called adversaries. Cryptography allows the sender and recipient of a message to read its details.

Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it.
Cryptography is the science of protecting information by transforming it into a secure format.

An example of basic cryptography is a encrypted message in which letters are replaced with other characters. To decode the encrypted contents, you would need a grid or table that defines how the letters are transposed
