md5加密c++跨平台

md5加密实现，c++ 跨平台，linux windows 都可以用static void MD5Init(MD5_CTX *context){  context->count[0] = 0;  context->count[1] = 0;  context->state[0] = 0x67452301;  context->state[1] = 0xEFCDAB89;  context->state[2] = 0x98BADCFE;  context->state[3] = 0x10325476;}static void MD5Update(MD5_CTX *context, unsigned char *input, unsigned int inputlen){  unsigned int i = 0;  unsigned int index = 0;  unsigned int partlen = 0;  index = (context->count[0] >> 3) & 0x3F;  partlen = 64 - index;  context->count[0] += inputlen << 3;  if(context->count[0] < (inputlen << 3))    context->count[1]++;  context->count[1] += inputlen >> 29;  if(inputlen >= partlen)  {  &n
