I'm trying to use TIdHashMessageDigest5, but whenever I call the
HashValue function, regardless of whether I send in a TStream* or an
AnsiString, an EAccessViolation exception is thrown. I've not been able
to figure out what's wrong with my code. I've included a sample of what
I've tried so far and would appreciated any suggestions you may have.

...
#include <IdHashMessageDigest.hpp>
...
void __fastcall TForm1::Button1Click(TObject* Sender) {
    TFileStream* File = NULL;
    TIdHashMessageDigest5* Hash = NULL;
    try {
        File = new TFileStream("c:\\boot.ini", fmOpenRead);
        Hash = new TIdHashMessageDigest5;
        Edit1->Text = Hash->HashValue(File);
    } catch(Exception& Ex) {
        Edit1->Text = Ex.Message;
    }
    if(Hash) delete Hash;
    if(File) delete File;
}
