Pure Rust implementation of the [MD2] cryptographic hash algorithm.

## Examples

```rust
use md2::{Md2, Digest};
use hex_literal::hex;

let mut hasher = Md2::new();
hasher.update(b"hello world");
let hash = hasher.finalize();

assert_eq!(hash, hex!("d9cce882ee690a5c1ce70beff3a78c77"));

// Hex-encode hash using https://docs.rs/base16ct
let hex_hash = base16ct::lower::encode_string(&hash);
assert_eq!(hex_hash, "d9cce882ee690a5c1ce70beff3a78c77");
```

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