  This demo is based on the GD32207i-EVAL-V1.2, it shows how to use the HAU
peripheral to hash data using SHA-1 and MD5 algorithms.
  The SHA-1 message digest result is a 160 bit data and the 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 up.  All result data can be displayed on the PC HyperTerminal using the USART, 
and the expected print results are as follows:

message to be hashed:
