       crypt: Fix hash line format compatibility
       
       According to the coreutils implementation man-page (of sha512sum),
       
       > The sums are computed as described in FIPS-180-2.  When checking, the
       > input should be a former output of this program.  The default mode is
       > to print a line with: checksum, a space, a character indicating input
       > mode ('*' for binary, ' ' for text or where binary is insignificant),
       > and name for each FILE.
