A copy of the license is included in the section entitled @node Overview @chapter Overview -Lorem Ipsum +@command{sha3sum} is a collection of utilities +around Keccak and its close derivatives SHA-3, +SHAKE and RawSHAKE for calculating checksums +and verifying the integrity of files. + +@command{sha3sum} is based on the library +@command{libkeccak} which is not optimised for +any particular microarchitecture. If you find +a library optimised for your microarchitecture, +not too much work should be required to make it +@command{libkeccak}-compatible, if it isn't +already; or alternatively, make @command{sha3sum} +compatible with that library. @node Invoking @chapter Invoking -Lorem Ipsum +@command{sha3sum} include a collection of +similar utilities: + +@table @command +@item keccak-224sum +Calculates Keccak-224 checksums, +which is Keccak[r=1152,c=448,n=224]. + +@item keccak-256sum +Calculates Keccak-256 checksums, +which is Keccak[r=1088,c=512,n=256]. + +@item keccak-384sum +Calculates Keccak-384 checksums, +which is Keccak[r=832,c=768,n=384]. + +@item keccak-512sum +Calculates Keccak-512 checksums, +which is Keccak[r=576,c=1024,n=512]. + +@item keccaksum +Calculates Keccak[] checksums, +which is Keccak[r=1024,c=576,n=512]. + +@item sha3-224sum +Calculates SHA3-224 checksums. + +@item sha3-256sum +Calculates SHA3-256 checksums. + +@item sha3-384sum +Calculates SHA3-384 checksums. + +@item sha3-512sum +Calculates SHA3-512 checksums. + +@item rawshake256sum +Calculates RawSHAKE-256 checksums. + +@item rawshake512sum +Calculates RawSHAKE-512 checksums. + +@item shake256sum +Calculates SHAKE-256 checksums. + +@item shake512sum +Calculates SHAKE-512 checksums. +@end table + +The @command{sha3sum} utilities recognises the +following options, and takes takes any number +of files. + +@table @option +@item -- +Parse all following arguments as filenames. + +@item ++ +Parse the next argument as a filename. + +@item -h +@itemx --help +Display a summary of options. + +@item -u +@itemx --upper +@itemx --uppercase +@itemx --upper-case +Output the checksums in upper case hexadecimal. + +@item -l +@itemx --lower +@itemx --lowercase +@itemx --lower-case +Output the checksums in lower case hexadecimal. + +@item -b +@itemx --binary +Output the checksums in binary format.
