May 21, 2018 In this video we'll be learning how to create our own license keys using Python, we'll also be using our own algorithm to verify keys we create. Go to for more! HMAC-based One-time Password algorithm (HOTP) is a one-time password (OTP) algorithm based on hash-based message authentication codes (HMAC). It is a cornerstone of the Initiative for Open Authentication (OATH). HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation. Since then, the algorithm has been.

TOTP Generation base on time and user identification
Time-based One-time Password Algorithm which computes a one-time password from shared key(in our case, the user id) and a DateTime.
TOTP is an example of a hash-based message authentication code (HMAC). It combines a secret key with the current timestamp using a cryptographic hash function to generate a one-time password. The timestamp typically increases in 30-second intervals, so passwords generated close together in time from the same secret key will be equal.
TOTP is based on HOTP with a timestamp replacing the incrementing counter.
It has been adopted as Internet Engineering Task Force standard RFC 6238.(RFC 4226 for HOTP)

Requirements
- Microsoft .NET Framework 4.0
Usage
// TOTP algorithm uses HOTP
// Call TOTP service /generate-rsa-key-for-different-user.html.
string otp = _totp.GenerateOtp(keyBytes, dateTime);
Python Code Generator
// Call generate password service
var password GeneratePassword(userId, dateTime)
