Cryptography is the science of transforming data using a key such that the data is unintelligible to those who do not have the key. The primitive operation at the disposal of cryptography is encryption. Encryption is used to provide message privacy and integrity. It has helped in the past to ensure secrecy in important communication especially in military and diplomatic sectors. The different algorithm used in cryptography techniques will be highlighted and one of the applications would be presented using a Object Oriented programming language (OOP) to implement.
