    onceler

    A One-Time-Password library for node.js

    TOTP

    var TOTP = require('onceler').TOTP;
    
    // create a TOTP object for a given base-32 encoded secret.
    var totp = new TOTP('IFAUCQKCIJBEE===');
    
    // get the password at a specified time index
    console.log(totp.at(650269));
    
    // get the password for the current time
    console.log(totp.now());
    
    // verify a user supplied password
    if(totp.verify(1234567)) {
        console.log('access granted!');
    } else {
        console.log('access denied!');
    }
    

    OTP digit size and time interval can be specified as such:

    // 60 second interval
    var totp = new TOTP('IFAUCQKCIJBEE===', null, 60);
    
    // 12 digit size
    var totp = new TOTP('IFAUCQKCIJBEE===', 12);
    
    // both
    var totp = new TOTP('IFAUCQKCIJBEE===', 12, 60);
    

    HOTP

    HOTP is also supported.

    var HOTP = require('onceler').HOTP;
    
    // create an HOTP object for a given base-32 encoded secret.
    var hotp = new HOTP('IFAUCQKCIJBEE===');
    
    // hotp.verify(password, count)
    if(hotp.verify(581561, 0)) {
        console.log('access granted!');
    } else {
        console.log('access denied!');
    }
    
    if(hotp.verify(224556, 1)) {
