Struct TOTP 

pub struct TOTP { /* private fields */ }

TOTP generator and validator.

Secret is securely zeroized from memory when dropped.

Implementations

impl TOTP

pub fn new(secret: Vec<u8>, digits: usize, interval: u64) -> Self

Create new TOTP with secret.

pub fn with_secret(secret: Vec<u8>) -> Self

Create with default settings (6 digits, 30 second interval).

pub fn generate_secret() -> Result<Vec<u8>>

Generate a random secret.

pub fn generate(&self, timestamp: Option<u64>) -> String

Generate TOTP code for given time.

pub fn verify(&self, code: &str, timestamp: Option<u64>, window: u32) -> bool

Verify TOTP code with time window.

pub fn secret_to_base32(secret: &[u8]) -> String

Convert secret to Base32.

pub fn secret_from_base32(encoded: &str) -> Result<Vec<u8>>

Decode Base32 secret.

pub fn provisioning_uri(&self, account: &str, issuer: &str) -> String

Generate provisioning URI for QR codes.

pub fn secret(&self) -> &[u8]

Get the secret.

Trait Implementations

impl Drop for TOTP

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for TOTP

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
