An implementation of the [SHA-3][1] cryptographic hash algorithms.
There are 6 standard algorithms specified in the SHA-3 standard:
* `SHA3-224`
* `SHA3-256`
* `SHA3-384`
* `SHA3-512`
* `SHAKE128`, an extendable output function (XOF)
* `SHAKE256`, an extendable output function (XOF)
* `Keccak224`, `Keccak256`, `Keccak384`, `Keccak512` (NIST submission
without padding changes)
# Usage
An example of using `SHA3-256` is:
```rust
# #[macro_use] extern crate hex_literal;
# extern crate sha3;
# fn main() {
use sha3::{Digest, Sha3_256};
// create a SHA3-256 object
let mut hasher = Sha3_256::new();
// write input message
hasher.input(b"abc");
// read hash digest
let result = hasher.result();
assert_eq!(result[..], hex!("
3a985da74fe225b2045c172d6bd390bd855f086e3e9d525b46bfe24511431532
")[..]);
# }
```
