NAME

       md5sum - compute and check MD5 message digest

SYNOPSIS

       md5sum [OPTION]... [FILE]...

DESCRIPTION

       Print or check MD5 (128-bit) checksums.

       With no FILE, or when FILE is -, read standard input.

       -b, --binary
              read in binary mode

       -c, --check
              read MD5 sums from the FILEs and check them

       --tag  create a BSD-style checksum

       -t, --text
              read in text mode (default)

   The following five options are useful only when verifying checksums:
       --ignore-missing
              don't fail or report status for missing files

       --quiet
              don't print OK for each successfully verified file

       --status
              don't output anything, status code shows success

       --strict
              exit non-zero for improperly formatted checksum lines

       -w, --warn
              warn about improperly formatted checksum lines

       --help display this help and exit

       --version
              output version information and exit

       The  sums  are  computed as described in RFC 1321.  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.

BUGS

       The  MD5  algorithm  should  not  be used any more for security related purposes.  Instead, better use an
       SHA-2 algorithm, implemented in the programs sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1)
