sha256 中digest用mmcau和其他软件库运行结果不一样问题。

 

首先,我使用mmcau用算sha256:

/* SHA test string: "The quick brown fox jumps over the lazy dog"
* with padding bits included
*/
static uint8_t g_testSha[64] = {0x54, 0x68, 0x65, 0x20, 0x71, 0x75, 0x69, 0x63, 0x6b, 0x20, 0x62, 0x72, 0x6f,0x77, 0x6e, 0x20, 0x66, 0x6f, 0x78, 0x20, 0x6a, 0x75, 0x6d, 0x70, 0x73, 0x20,
0x6f, 0x76, 0x65, 0x72, 0x20, 0x74, 0x68, 0x65, 0x20, 0x6c, 0x61, 0x7a, 0x79,
0x20, 0x64, 0x6f, 0x66, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x58};

绿色的是“The quick brown fox jumps over the lazy dog”,红色的那一段是运算中干什么的?

用软件实现sha256,输入的是“The quick brown fox jumps over the lazy dog”,共43个字符,digest is:d7a8fbb37d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592

 

但是,若“The quick brown fox jumps over the lazy dog€.................. X”,这个是64个字符,软件digest is:66092d3c2467b3373e11bb0d2618f935213348ab61e115895402a133e6c5631e

mmcau  digest is: d7a8fbb37d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592.

 

这,是怎么回事????运算“The quick brown fox jumps over the lazy dog”硬件mmcau为何还要后面一段“€.................. X”
