  This demo is based on the GD32H759I-EVAL-V1.1 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.
  The all result data can be displayed on a PC HyperTerminal using the USART.
