  This demo is based on the GD32VW553H-EVAL-V1.2 board, it shows how to use the HAU
peripheral to hash data using HMAC SHA-1 and HMAC MD5 algorithms.
  The key used is long type(2088 bit data).
The HMAC SHA-1 message digest result is a 160 bit data and the HMAC MD5 message
digest result is a 128 bit data.
  If the hash calculation results are consistent with the expected result, then 
the LED1 will light upThe all result data can be displayed on a PC HyperTerminal 
using the USART.
