sha3sum - Print or Check SHA-3 Checksums
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 -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 -p, --portable read in portable mode (to be deprecated) The following two options are useful only when verifying checksums: -s, --status don't output anything, status code shows success -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, `?' for portable), and name for each FILE.

DESCRIPTIONRunning sha3sum is often the quickest way to compute SHA-3 message digests. The user simply feeds data to the script through files or standard input, and then collects the results from standard output.
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
