# The SHA-3 (Keccak) extension for Ruby
Digest::Keccak
==============
This Ruby extension implements the SHA-3 ([Keccak](http://keccak.noekeon.org/)) cryptographic hashing algorithm. It is based on the reference C implementation, version 3.2. The exposed interface is almost identical to that of the `digest` standard library.

## Installation
gem install digest-sha3
**Note**: as of version 1.1.0, digest-sha3 requires Ruby 2.2. The last version that worked on older versions was 1.0.2.
Usage
-----
## Usage
Keccak supports 5 hash lengths: 224-bit, 256-bit, 384-bit, 512-bit and variable length. Variable length is not supported by this Ruby extension. Unless the user specifies otherwise, this Ruby extension assumes 512-bit.

## Running the test suite
Running the test suite
----------------------
Run the test suite as follows:
```
make test
```
A part of the test suite is automatically generated from Keccak's reference test suite.
## Warning
Do not use SHA-3 for hashing passwords. Do not even use SHA-3 + salt for hashing passowords. Use a [slow hash](http://codahale.com/how-to-safely-store-a-password/) instead.
