**SHA-3/Keccak checksum calculator**

*USAGE:*

    sha3sum [option...] < FILE
    sha3sum [option...] file...

*OPTIONS:*

    -r BITRATE
    --bitrate      The bitrate to use for SHA-3.          (default: 576)
    
    -c CAPACITY
    --capacity     The capacity to use for SHA-3.         (default: 1024)
    
    -w WORDSIZE
    --wordsize     The word size to use for SHA-3.        (default: 64)
    
    -o OUTPUTSIZE
    --outputsize   The output size to use for SHA-3.      (default: 512)
    
    -s STATESIZE
    --statesize    The state size to use for SHA-3.       (default: 1600)
    
    -i ITERATIONS
    --iterations   The number of hash iterations to run.  (default: 1)
    
    -b
    --binary       Print the checksum in binary, rather than hexadecimal.


If you want to contribute with an implementation in another
language, please try do some 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.
