Two-step verification of HOTP/TOTP for Rust.

## Installation

Add it to your ``Cargo.toml``:

```toml

[dependencies]

otpauth = "0.5"

```

## Examples

### HOTP example

```rust

use otpauth::HOTP;

fn main() {

    let auth = HOTP::new("python");

    let code = auth.generate(4);

    assert_eq!(true, auth.verify(code, 0, 100));

}

```

### TOTP example

```rust

use std::time::{SystemTime, UNIX_EPOCH};

use otpauth::TOTP;

fn main() {

    let auth = TOTP::new("python");

    let timestamp1 = SystemTime::now().duration_since(UNIX_EPOCH)?.as_secs();

    let code = auth.generate(30, timestamp1);

    let timestamp2 = SystemTime::now().duration_since(UNIX_EPOCH)?.as_secs();

    assert_eq!(true, auth.verify(code, 30, timestamp2));

}

```
