The code can actually do -a XOF of arbitrary size (like "SHAKE512"). - - -### Updated 03-Sep-15: - -Made the implementation portable. The API is now pretty much the -same that OpenSSL uses. - - -### Updated 07-Aug-15: - -Now that SHA3 spec is out, I've updated the package to match with the -new padding rules. There is literally one line difference between -Keccak 3.0 and SHA-3 implementations: - -``` - temp[inlen++] = 0x06; // XXX Padding Changed from Keccak 3.0 -``` - -The 0x06 constant there used to be 0x01. But this of course totally -breaks compatibility and test vectors had to be revised. - -SHA-3 Spec: http://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.202.pdf - -Cheers, -- markku - - -### Original README.TXT from 19-Nov-11: - -Hi. - -The SHA-3 competition is nearing it's end and I would personally like -to support Keccak as the winner. I have a PhD in hash function cryptanalysis -so don't take my word for it, go ahead and look into the code ! - -Since I couldn't find a *compact* and/or *readable* implementation of Keccak -anywhere, here's one I cooked up as a service to the curious. - -This implementation is intended for study of the algorithm, not for -production use. - -The code works correctly on 64-bit little-endian platforms with gcc. -Like your Linux box. The main.c module contains self-tests for all -officially supported hash sizes. - -If you're looking for production code, the official multi-megabyte package -covers everyting you could possibly need and too much much more: -http://keccak.noekeon.org/ - -Cheers, -- Markku 19-Nov-11 - -Dr. Markku-Juhani O.
