Struct boringauth::oath::TOTP

pub struct TOTP { /* fields omitted */ }

Methods

impl TOTP

pub fn generate(&self) -> String

Generate the current TOTP value.

Examples

let key_base32 = "GEZDGNBVGY3TQOJQGEZDGNBVGY3TQOJQ".to_owned();
let mut totp = boringauth::oath::TOTPBuilder::new()
    .base32_key(&key_base32)
    .finalize()
    .unwrap();

let code = totp.generate();
assert_eq!(code.len(), 6);

pub fn is_valid(&self, code: &String) -> bool

Checks if the given code is valid. This implementation uses the double HMAC verification in order to prevent a timing side channel attack.

Examples

let key_ascii = "12345678901234567890".to_owned();
let user_code = "755224".to_owned();
let valid = boringauth::oath::TOTPBuilder::new()
    .ascii_key(&key_ascii)
    .finalize()
    .unwrap()
    .is_valid(&user_code);
