-1只是用来举例而已
该Flash的MD5转换中有许多这样的代码:a = md5_ff(a, b, c, d, x[i+0], 7, -680876936);
d = md5_ff(d, a, b, c, x[i+1], 12, -389564586);
c = md5_ff(c, d, a, b, x[i+2], 17, 606105819);
b = md5_ff(b, c, d, a, x[i+3], 22, -1044525330);
a = md5_ff(a, b, c, d, x[i+4], 7, -176418897);
d = md5_ff(d, a, b, c, x[i+5], 12, 1200080426);
c = md5_ff(c, d, a, b, x[i+6], 17, -1473231341);
b = md5_ff(b, c, d, a, x[i+7], 22, -45705983);
a = md5_ff(a, b, c, d, x[i+8], 7, 1770035416);

右边那些常熟有很多是负数
一个一个的改起来太麻烦了 |
