&par Example Description

This example describes  the CRYP processor performs data encryption and decryption using
AES lgorithms in Electronic codebook (ECB) or Cipher block chaining (CBC)  or counter(CTR)
mode.The data that needs to be decrypted and encrypted will be displayed on the serial
 assistant through USART1.

if define AES_TEXT_SHORT then the length of plaintext is 64， else the length of plaintext is 128

&par Hardware Description

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled
