AES encryption and decryption,
AES is a type of symmetric encryption. It is simply understood that there is only one key, and it is used for encryption and decryption. The security is not very good.

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
