-Cryptography is the art and science of keeping massages secure. It is the study of techniques related to aspects of information security such as information privacy, integrity, authentication and non-repudiation. Cryptography is almost synonymous with encryption i.e. the conversion of plain text to a cryptic text to secure it against unauthorized users. Encryption techniques are typically divided into two generic types: symmetric key encryption and asymmetric key encryption. Encryption methods in which both the sender and receiver share the same key are referred to as symmetric key encryption schemes. Encryption methods in which encryption and decryption are performed using the different keys, one a public key and one a private key are referred to as asymmetric key encryption schemes. This paper provides a performance comparison between four popular and commonly used encryption algorithms: DES, 3DES, AES, and RSA. DES, 3DES, and AES are symmetric key encryption algorithms while as RSA is an asymmetric key encryption algorithm.
