/**
This is a easy and safe interface to MD5-calculation.
To get a MD5-sum of data, instantiate a md5stream, copy your data
into it and read the digest.
After calling getDigest or getHexDigest, the class can be reused
for another md5-calculation. The algorithm is automatically
reinitialized when the first character is received.
example:
\code
int main(int argc, char* argv[])
{
Md5stream s;
for (int i = 1; i < argc; ++i)
{
std::ifstream in(argv[i]);
if (in)
{
s << in.rdbuf();
std::cout << s.getHexDigest() << " " << argv[i] << std::endl;
}
}
