  This demo is based on the GD32207i-EVAL-V1.2 board, it shows how to use the HAU
peripheral to hash data using SHA-1 and MD5 Algorithms.
  For this example, DMA is used to transfer data from memory to the HAU processor.
The message to hash is a 2040 bit data, the SHA-1 message digest result is a 160 
bit data and the MD5 message digest result is a 128 bit data.
  JP5 must be jumpped to USART.
  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:

The GD32 F2 series is the result of a perfect symbiosis of the real-time control capabilities of an MCU and the signal processing performance of a DSP, and thus complements the GD32 portfolio with a new class of devices, digital signal controllers (DSC). 

SHA1 message digest (160 bits):

0xd03e020b
0xa75f3aca
0xf9eb955
0x701e6baf
0xc2ca3530
 

MD5 message digest (128 bits):

0xe9cbb679
0x6e6700bd
0xd1010b9f
0x60929cae
