How would I create a method like toString() within the SHA-1 class to convert a message digest to a C++ string, each representing a hexadecimal digit.
Also, how could specify whether a file should be read as a text file or binary file?
Thanks

Try using a stringstream with the hex modifier:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
ostringstream oss;
char ch = 'a';
cout<< ch <<" -- "<< hex << static_cast<int> ( ch ) <<endl;
oss<< ch <<" -- "<< hex << static_cast<int> ( ch );
cout<< oss.str() <<endl;
}

Text orientation is the default. If you want binary then add ios::binary or ios_base::binary to the mode:
ifstream in ( filename, ios::binary );
