### Updated 19-Jul-19:
This is a CUDA port of tiny_sha3, which also now includes mining specific calls for use by the cruzbit client.
Original project's README follows.

# tiny_sha3
Very small, readable implementation of the FIPS 202 and SHA3 hash function.
Public domain.
### Updated 27-Dec-15:
Added SHAKE128 and SHAKE256 code and test vectors. 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.

### 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:
