Java encryption technology (II) -- symmetric encryption algorithm des & AES

From: http://snowolf.iteye.com/blog/380034 Next, we will introduce symmetric encryption algorithms. The most common is des data encryption algorithms.Des Des-Data Encryption Standard, which is the data encryption algorithm. It was published by IBM in 1975. The DES algorithm has three entry parameters: Key, data, and mode. Among them, the key is 8 bytes in 64-bit, which is the key of the DES algorithm; data is also 8 bytes in 64-bit, which is the data to be encrypted or decrypted; the mode is des
