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.

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
