NAME

SYNOPSIS

 Usage: sha3sum [OPTION]... [FILE]...
 Print or check SHA-3 checksums.
 With no FILE, or when FILE is -, read standard input.

   -a, --algorithm   224 (default), 256, 384, 512, 128000, 256000
   -b, --binary      read in binary mode
   -c, --check       read SHA-3 sums from the FILEs and check them
       --tag         create a BSD-style checksum
   -t, --text        read in text mode (default)
   -U, --UNIVERSAL   read in Universal Newlines mode
                         produces same digest on Windows/Unix/Mac
   -0, --01          read in BITS mode
                         ASCII '0' interpreted as 0-bit,
                         ASCII '1' interpreted as 1-bit,
                         all other characters ignored

 The following five options are useful only when verifying checksums:
       --ignore-missing  don't fail or report status for missing files
   -q, --quiet           don't print OK for each successfully verified file
   -s, --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

   -h, --help        display this help and exit
   -v, --version     output version information and exit

 The sums are computed as described in the FIPS 202 SHA-3 submission.
 When checking, the input should be a former output of this program.
 The default mode is to print a line with checksum, a character
 indicating type (`*' for binary, ` ' for text, `U' for UNIVERSAL,
 `^' for BITS), and name for each FILE.  The line starts with a `\'
 character if the FILE name contains either newlines or backslashes,
 which are then replaced by the two-character sequences `\n' and
 `\\' respectively.

DESCRIPTION

The following command shows how to compute digests for typical inputs such as the NIST test vector "abc":

        perl -e "print qq(abc)" | sha3sum

Or, if you want to use SHA3-256 instead of the default SHA3-224, simply say:

        perl -e "print qq(abc)" | sha3sum -a 256

Unlike many other digest computation programs, sha3sum implements the full SHA-3 standard by allowing partial-byte inputs, which can be recognized through the BITS option (-0). The following example computes the SHA3-384 digest of the 7-bit message 0001100:

        perl -e "print qq(0001100)" | sha3sum -0 -a 384
