# RustCrypto: FSB

Pure Rust implementation of the [FSB] cryptographic hash algorithms.

There are 5 standard versions of the FSB hash function:

* `FSB-160`
* `FSB-224`
* `FSB-256`
* `FSB-384`
* `FSB-512`

## Examples

Output size of FSB-256 is fixed, so its functionality is usually
accessed via the `Digest` trait:

```rust
use fsb::{Digest, Fsb256};
use hex_literal::hex;

let mut hasher = Fsb256::new();
hasher.update(b"hello");
let hash = hasher.finalize();

assert_eq!(hash, hex!("0f036dc3761aed2cba9de586a85976eedde6fa8f115c0190763decc02f28edbc"));

// Hex-encode hash using https://docs.rs/base16ct
let hex_hash = base16ct::lower::encode_string(&hash);
assert_eq!(hex_hash, "0f036dc3761aed2cba9de586a85976eedde6fa8f115c0190763decc02f28edbc");
```

Also, see the [examples section] in the RustCrypto/hashes readme.
