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!

How to use

Add it to your Cargo.toml:

[dependencies]
totp-rs = "~0.2"

You can then do something like:

use totp_rs::{TOTP, Algorithm};
use std::time::SystemTime;

let username = "example".to_string();
let totp = TOTP::new(Algorithm::SHA1, 6, 1, 30, "supersecret".to_string().into_bytes());
let time = SystemTime::now().duration_since(SystemTime::UNIX_EPOCH)?.as_secs();
let url = totp.get_url(format!("account:{}", username), "my-org.com".to_string());
println!("{}", url);
let token = totp.generate(time);
println!("{}", token);
