SHA-3 has not been standardised yet! --------------------------------------------------------------------- Checksum utility for Keccak and its close derivatives SHA-3, SHAKE and RawSHAKE. --------------------------------------------------------------------- Performance benchmark on a 1 GiB file (yes, that is quite large) with /dev/urandom data: $ keccak-224sum real 0m9.550s user 0m9.223s sys 0m0.320s $ keccak-256sum real 0m9.841s user 0m9.560s sys 0m0.260s $ keccak-384sum real 0m12.902s user 0m12.580s sys 0m0.313s $ keccak-512sum real 0m18.084s user 0m17.823s sys 0m0.243s $ keccaksum real 0m10.438s user 0m10.140s sys 0m0.287s $ sha1sum real 0m3.421s user 0m3.157s sys 0m0.253s $ sha224sum real 0m8.196s user 0m7.910s sys 0m0.263s $ sha256sum real 0m9.361s user 0m9.097s sys 0m0.257s $ sha384sum real 0m5.450s user 0m5.223s sys 0m0.220s $ sha512sum real 0m4.507s user 0m4.247s sys 0m0.257s $ md5sum real 0m2.987s user 0m2.703s sys 0m0.283s $ md6sum real 1m28.873s user 1m28.470s sys 0m0.360s Note: The times are a bit random, and only one run has been made. "user" is the most interesting data. Additionally, only the pure keccak variants have been tested because the difference is between them and the other are quite small; and of course the other hashing utilities from other packages using other algorithm-families. --------------------------------------------------------------------- The implementation of the algorithms is done in libkeccak (https://github.com/maandree/libkeccak), so to verify that this program is correct, verify libkeccak using its test suite (https://github.com/maandree/libkeccak/blob/master/src/test.c) and check that some of hashes are returned identically by sha3sum.
