• # totp-rs
  
  This library permits the creation of 2FA authentification tokens per TOTP, the verification of said tokens, with configurable time skew, validity time of each token, algorithm and number of digits! With additional feature "qr", you can use it to generate a base64 png qrcode.
  
  ## How to use
  
  Add it to your `Cargo.toml`:
  ```toml
  [dependencies]
  totp-rs = "~0.4"
  ```
  You can then do something like:
  ```Rust
  use std::time::SystemTime;
  use totp_rs::{Algorithm, TOTP};
  
  let totp = TOTP::new(
      Algorithm::SHA1,
      6,
      1,
      30,
      "supersecret".to_owned().into_bytes(),
  );
  let time = SystemTime::now()
      .duration_since(SystemTime::UNIX_EPOCH).unwrap()
      .as_secs();
  let url = totp.get_url("user@example.com", "my-org.com");
  println!("{}", url);
  let token = totp.generate(time);
  println!("{}", token);
  ```
  
  ### With qrcode generation
  
  Add it to your `Cargo.toml`:
  ```toml
  [dependencies.totp-rs]
  version = "~0.4"
  features = ["qr"]
  ```
  You can then do something like:
  ```Rust
  use totp_rs::{Algorithm, TOTP};
  
  let totp = TOTP::new(
      Algorithm::SHA1,
      6,
      1,
      30,
      "supersecret".to_owned().into_bytes(),
  );
  let code = totp.get_qr("user@example.com", "my-org.com")?;
  println!("{}", code);
  ```
