#332 in Authentication
34KB
749 lines
totp-sos
This library supports 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 lightweight as possible to ensure small binaries and short compilation time.
Supports parsing otpauth URLs into a totp object, with sane default values.
Be aware that some authenticator apps will accept the SHA256
and SHA512
algorithms but silently fallback to SHA1
which will make the check()
function fail due to mismatched algorithms.
Derived from the totp-rs crate with a simpler API and fewer dependencies.
Features
zeroize
Securely zero secret information when the TOTP struct is dropped; this feature is enabled by default.
serde
Optional feature serde
, enables serde support for the TOTP
and Algorithm
types.
Generate a token
use std::time::SystemTime;
use totp_rs::{Algorithm, TOTP, Secret};
fn main() {
let totp = TOTP::new(
Algorithm::SHA1,
6,
1,
30,
"TestSecretSuperSecret".as_bytes().to_vec(),
"mock@example.com".to_string(),
Some("Mock issuer".to_string()),
).unwrap();
let token = totp.generate_current().unwrap();
println!("{}", token);
}
