Two-step verification of HOTP/TOTP for Rust.

## Installation

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

```toml
[dependencies]
otpauth = "*"
```

Add ``extern crate otpauth`` to your crate root and your're good to go!

## Examples

### HOTP example

```rust
extern crate otpauth;

use otpauth::OtpAuth;

fn main() {
    let auth = OtpAuth::new("python");
    let code = auth.hotp(4);
    assert_eq!(true, auth.valid_hotp(code, 0, 100));
}
```

### TOTP example

```rust
extern crate otpauth;
extern crate time;

use otpauth::OtpAuth;

fn main() {
    let auth = OtpAuth::new("python");
    let timestamp1 = time::now().to_timespec().sec as usize;
    let code = auth.totp(30usize, timestamp1);
    let timestamp2 = time::now().to_timespec().sec as usize;
    assert_eq!(true, auth.valid_totp(code, 30usize, timestamp2));
}
```
