In the field of computer security there are a large number of papers discussing on the topic of cryptography. Cryptography is an art of sending data to the intended recipient by preserving the integrity, confidentiality and authenticity of the data. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide information in storage or transit. However, in today's computer-centric world, cryptography is most often associated with converting plain-text (ordinary text, also referred as clear-text) into cipher-text (by a process called encryption), then back again (by a process known as decryption) to plain-text that is the original message. The main objectives of cryptography are Confidentiality (the message cannot by understood by anyone other than the intended recipient), Integrity (the message cannot be altered during its storage or transmission.), Non- repudiation (the creator/sender of the information cannot deny at a later stage his or her intentions in the creation or transmission of the information), Authentication (the sender and receiver can confirm each other’s identity and the origin/destination of the information).
