Here is a minimal example:
string data(
"0123456789"
"0123456789"
"0123456789"
"0123456789"
"0123456789"
"0123456789"
"0123456789");
string output;
SHA1 sha;
stringstream source;
FileSource filter(source, false, new HashFilter(sha, new
StringSink(output), true));
source << data.substr(0, 62);
filter.Pump();
source.clear();
source.str("");
source << data.substr(62);
filter.Pump();
source.clear();
source.str("");
filter.AttachedTransformation()->MessageEnd();
cout << output.substr(0, 70) << endl;
The output is
0123456789012345678901234567890123456789012345678901234567890110456789
(with line breaks for readability)
0123456789
0123456789
0123456789
0123456789
0123456789
0123456789
0110456789
Note byte 63, 64 are actually 61, 62 in reverse order.
