Description: Symmetric algorithm, also known as the traditional cryptographic algorithms. Reflected in the symmetry of symmetric algorithm encryption key can decrypt the keys derived from, and vice versa. In most symmetric algorithms, encryption and decryption key are the same. Visible, symmetric key encryption algorithm key are confidential. Symmetric key algorithm is divided into two block ciphers and stream ciphers. Cipher the plaintext is divided into a number of fixed-length blocks of data called a packet, each packet processing on a stream cipher, also known as cipher, each element in turn for processing the input. DES algorithm is a symmetric key algorithm is the most common, is block cipher.
