The pass phrase input routine reads from the consol not from the standard
input.
I gess that it is more secure than reading from stdin.
Under Windows I managed to write the password to to the console.
It works but it is quite complicated and I don't know if it is possible to
do the same with unix.
There might be simpler ways...
