        "DESCRIPTION": {
            "content": "Running sha3sum is often the quickest way to compute SHA-3 message digests.  The user simply\nfeeds data to the script through files or standard input, and then collects the results from\nstandard output.\n\nThe following command shows how to compute digests for typical inputs such as the NIST test\nvector \"abc\":\n\nperl -e \"print qq(abc)\" | sha3sum\n\nOr, if you want to use SHA3-256 instead of the default SHA3-224, simply say:\n\nperl -e \"print qq(abc)\" | sha3sum -a 256\n\nUnlike many other digest computation programs, sha3sum implements the full SHA-3 standard by\nallowing partial-byte inputs, which can be recognized through the BITS option (-0).  The\nfollowing example computes the SHA3-384 digest of the 7-bit message 0001100:\n\nperl -e \"print qq(0001100)\" | sha3sum -0 -a 384\n",
