, according to 32 bits, is identified in turn as W0, W1,..., W79.3). a 1-word temp buffer .To calculate the message digest:In 3.2, we append the data of the complement to the length information and then divide it into a single 512-bit (16-word) block of data m1,m2,..., Mn, where each chunk of mi (1≤i≤n) is processed sequentially.Before processing each chunk of MI (1≤i≤n), initialize the buffer h0,h1,h2,h3,h4 to the following value (16 binary): H0 = 0x67452301H1 = 0xefcdab89H2 = 0x98badcfeH3 = 0
This question is not passed by a good brute force law. Next time I change it to KMP. It's still too weak to KMP... T ^ T also encountered a very strange problem, which is reflected in the Code annotations.

values to buffer a,b,c,d,e, respectively:
A=H[0]
B=H[1]
C=H[2]
D=H[3]
E=H[4]
D. For w[0]~w[79], let's go through the following loops:
TEMP = S5 (A) + ft (b,c,d) + E + w[i] + k[i]
E=d
D=c
C=S30 (B)
B=a
A=temp
E. We will then operate on buffer h[]:
H[0]=h[0]+a
H[1]=h[1]+b
H[2]=h[2]+c
H[3]=h[3]+d
H[4]=h[4]+e
3) After completing each m[i] cycle, the resulting message digest is:
H[0] h[1] h[2] h[3] h[4]
The values in buffer h[] are all converted to 16 dig
