pub struct TOTP { /* fields omitted */ }

Provides Time based One Time Passwords.

  • This object implements utilities for RFC6328.

Methods

impl TOTP[src]

pub fn new(secret: HOTP, time_step: u64, start_time: u64) -> TOTP[src]

Creates a new TOTP instance.

Arguments

  • secret - HOTP secret to use for TOTP generation.
  • time_step - The time frame to allow every password, in seconds. RFC6238 recommends 30 seconds.
  • start_time - Configurable T0 for OTP.

pub fn get_otp(&self, digits: u32, offset: i32) -> u32[src]

Generates a time based OTP.

Arguments

  • digits - Desired OTP length, should be at least 6.
  • offset - Should be 0 for current time frame, -1 for previous, 1 for next, etc...

pub fn validate(&self, digits: u32, guess: u32, buffer: u32) -> bool[src]

Validates the given OTP.

Arguments

  • digits - The amount of digits set for the OTP.
  • guess - The user provided guess to validate.
  • buffer - Amount of OTPs to check before and after the current one (0=Only current, 1=Previous+Now+Next OTP, etc...)
