-**SHA-3/Keccak checksum calculator**
-
-*USAGE:*
-
- sha3sum [option...] < FILE
- sha3sum [option...] file...
-
-*OPTIONS:*
-
- -r BITRATE
- --bitrate The bitrate to use for checksum. (default: 1024)
-
- -c CAPACITY
- --capacity The capacity to use for checksum. (default: 576)
-
- -w WORDSIZE
- --wordsize The word size to use for checksum. (default: 64)
-
- -o OUTPUTSIZE
- --outputsize The output size to use for checksum. (default: 512)
-
- -s STATESIZE
- --statesize The state size to use for checksum. (default: 1600)
-
- -i ITERATIONS
- --iterations The number of hash iterations to run. (default: 1)
-
- -j SQUEEZES
- --squeezes The number of hash squeezes to run. (default: 1)
-
- -x
- --hex Read the input in hexadecimal, rather than binary.
-
- -b
- --binary Print the checksum in binary, rather than hexadecimal.
-
- -m
- --multi Print the checksum at all iterations.
-
-
-**Pending the standardisation of SHA-3**, there is no specification of particular
-SHA-3 functions yet. Our defaults are based on Keccak[] being Keccak[r = 1024, c = 576]
-rather than the functions in Wikipedia's entires that uses [r = 576, c = 1024].
-No release will made until SHA-3 has been standardise, this is to prevent the
-program to change behaviour caused by mismatch with standardisation.
-
-
-If you want to contribute with an implementation in another
-language, please try do so in the earliest version of the
-language officially supported on GNU/Linux, unless there are
-backwards incompatibilities (as is the case with Python.)
-This helps for embedded devices.
