Crate 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! Default features are kept as low-dependency as possible to ensure small binaries and short compilation time

Examples

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

let totp = TOTP::new(
    Algorithm::SHA1,
    6,
    1,
    30,
    "supersecret",
);
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);

use totp_rs::{Algorithm, TOTP};

let totp = TOTP::new(
    Algorithm::SHA1,
    6,
    1,
    30,
    "supersecret",
);
let code = totp.get_qr("user@example.com", "my-org.com").unwrap();
println!("{}", code);

Structs

TOTP

TOTP holds informations as to how to generate an auth code and validate it. Its secret field is sensitive data, treat it accordingly

Enums

Algorithm

Algorithm enum holds the three standards algorithms for TOTP as per the reference implementation
