In this paper, the authors describe the cryptography and the various techniques of cryptography to encrypt the data. Cryptography is an art that is used to convert the text into unreadable form. The symmetric cryptography techniques use the same key for encryption and decryption while the asymmetric cryptography uses different keys for encryption and decryption. The paper compares the symmetric and the asymmetric cryptography. The Advanced Encryption Standard (AES) cryptography is also described in the paper.
