# tiny_sha3
|
|
Very small, readable implementation of the SHA3 hash function.
|
|
Updated 03-Sep-15:
|
|
|
|
Made the implementation portable. The API is now pretty much the
|
|
same that OpenSSL uses. Public domain.
|
|
|
|
|
|
### 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.

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:
