File name: SM3.c
Version: SM3_V1.1

Description: to calculate a hash message from a given message
Function List:
1.SM3_256 //calls SM3_init, SM3_process and SM3_done to calculate hash value
2.SM3_init //init the SM3 state
3.SM3_process //compress the the first len/64 blocks of the message
4.SM3_done //compress the rest message and output the hash value
5.SM3_compress //called by SM3_process and SM3_done, compress a single block of message
6.BiToW //called by SM3_compress,to calculate W from Bi
7.WToW1 //called by SM3_compress, calculate W1 from W
8.CF //called by SM3_compress, to calculate CF function.
9.BigEndian //called by SM3_compress and SM3_done.GM/T 0004-2012 requires to use
big-endian.
//if CPU uses little-endian, BigEndian function is a necessary call to
change the
//little-endian format into big-endian format.
10.SM3_SelfTest //test whether the SM3 calculation is correct by comparing the hash result
with the standard result

Modification: 1)add notes to all the functions
2)add SM3_SelfTest function
