Identical to hasher.cpp, but uses Pipe in a different way.
|
|
|
|
Note this tends to be much less efficient than hasher.cpp, because it
|
|
does three passes over the file. For a small file, it doesn't really
|
|
matter. But for a large file, or for something you can't re-read
|
|
easily (socket, stdin, ...) this is a bad idea.
