NAME

6       sha3sum - Print or Check SHA-3 Checksums

SYNOPSIS

9        Usage: sha3sum [OPTION]... [FILE]...
10        Print or check SHA-3 checksums.
11        With no FILE, or when FILE is -, read standard input.
12
13          -a, --algorithm   224 (default), 256, 384, 512, 128000, 256000
14          -b, --binary      read in binary mode
15          -c, --check       read SHA-3 sums from the FILEs and check them
16              --tag         create a BSD-style checksum
17          -t, --text        read in text mode (default)
18          -U, --UNIVERSAL   read in Universal Newlines mode
19                                produces same digest on Windows/Unix/Mac
20          -0, --01          read in BITS mode
21                                ASCII '0' interpreted as 0-bit,
22                                ASCII '1' interpreted as 1-bit,
23                                all other characters ignored
24
25        The following five options are useful only when verifying checksums:
26              --ignore-missing  don't fail or report status for missing files
27          -q, --quiet           don't print OK for each successfully verified file
28          -s, --status          don't output anything, status code shows success
29              --strict          exit non-zero for improperly formatted checksum lines
30          -w, --warn            warn about improperly formatted checksum lines
31
32          -h, --help        display this help and exit
33          -v, --version     output version information and exit
34
35        The sums are computed as described in the FIPS 202 SHA-3 submission.
36        When checking, the input should be a former output of this program.
37        The default mode is to print a line with checksum, a character
38        indicating type (`*' for binary, ` ' for text, `U' for UNIVERSAL,
39        `^' for BITS), and name for each FILE.  The line starts with a `\'
40        character if the FILE name contains either newlines or backslashes,
41        which are then replaced by the two-character sequences `\n' and
42        `\\' respectively.

DESCRIPTION

47       Running sha3sum is often the quickest way to compute SHA-3 message
48       digests.  The user simply feeds data to the script through files or
49       standard input, and then collects the results from standard output.
50
51       The following command shows how to compute digests for typical inputs
52       such as the NIST test vector "abc":
53
54               perl -e "print qq(abc)" | sha3sum
55
56       Or, if you want to use SHA3-256 instead of the default SHA3-224, simply
57       say:
58
59               perl -e "print qq(abc)" | sha3sum -a 256
60
61       Unlike many other digest computation programs, sha3sum implements the
62       full SHA-3 standard by allowing partial-byte inputs, which can be
63       recognized through the BITS option (-0).  The following example
64       computes the SHA3-384 digest of the 7-bit message 0001100:
65
66               perl -e "print qq(0001100)" | sha3sum -0 -a 384
