Caching passphrase...

       --passphrase-fd n  Read  the  passphrase from file descriptor
n.  Only the first  line will be read from file descriptor n.  If you use
0  for  n,  the passphrase will be read from stdin.  This can only
be  used if only one passphrase is supplied.
       --passphrase-file file  Read the passphrase from file file.
Only the first line will  be  read  from  file file.  This can only be
used if only one  passphrase is supplied.  Obviously, a
passphrase stored in  a  file is of questionable security if other
users can read this  file.  Don't use this option if you can avoid it.
       --passphrase string  Use string as the passphrase.  This can
only be used if  only  one passphrase is supplied.  Obviously, this
is of very ques-  tionable security on a multi-user  system.   Don't
use  this  option if you can avoid it.
