Entrance DES algorithm has three parameters: Key, Data, Mode. Key one of eight for a total of 64 bytes, are key job DES algorithm Data for 8-byte 64-bit is to be encrypted or decrypted data Mode work for DES, there are two types: encryption or decryption, if the Mode for encryption, the Key to the data with Data encryption, password Data generated forms of output as DES such as Mode for decryption, the Key to put the password used forms of data Data to decrypt and restore for Data the form of the code output as DES. In the use of DES, the two sides agreed in advance to use the " password" that is, Key, and then use the Key to encrypt data ciphertext recipient received the Key to use the same raw data to be decrypted, thus achieve a higher degree of safety data.
