Introduction

A symmetric encryption algorithm is a cryptosystem which is in contrast to an asymmetric encryption algorithm. A symmetric encryption algorithm uses the same cryptographic key both the encryption of information as for decrypting it. Such keys are mentioned symmetric keys. An example of a symmetric key is a session key. Some examples of symmetric encryption algorithms are AES, S-DES, IDEA, and RC4. Asymmetric encryption is a technique in cryptography that involves using two different keys: one open for others to encrypt and with its own private to decrypt. These keys are ...
