Lugnut

A One-time Password Crate for Rust

Lugnut is still experimental and under construction.

Lugnut is a one-time password generator that supports specification compliant HOTP and TOTP generation and verification.

Examples

Add to Cargo.toml

toml [dependencies] lugnut = "0.1.0

HOTP

```rust use lugnut::hotp::Hotp;

let key = String::from("SuperSecretKey"); let counter = 100;

let mut hotp = Hotp::new(); let code = hotp.generate(key, counter).expect("error generating hotp"); let verified = hotp.verify(code, key, counter).expect("error verifying hotp");

assert!(verified); ```

TOTP

```rust use lugnut::totp::Totp;

let key = String::from("SuperSecretKey");

let mut totp = Totp::new(); let code = totp.generate(key).expect("error generating totp"); let verified = totp.verify(code, key).expect("error verifying totp"); assert!(verified); ```

Upcoming for Lugnut

• Better Test Coverage
• Support for OTP Auth Url generation
• Support for forward and backward window configuration for TOTP (currently only support one value that is used for both
