.SYNOPSIS
  Time-base One-Time Password Algorithm (RFC 6238)

.DESCRIPTION
  This is an implementation of the RFC 6238 Time-Based One-Time Password Algorithm draft 
  based upon the HMAC-based One-Time Password (HOTP) algorithm (RFC 4226). This is a time 
  based variant of the HOTP algorithm providing short-lived OTP values.
