OTP Generator

An implementation of the OTP generator algo in F#. This uses the standard time-based implementation according to RFC 6238 https://tools.ietf.org/html/rfc6238

Uses standard 6 digit/30 seconds.

Usage:

open Otp

let key = getUserKey // Save this to your DB and present to the user (usually done as a QR Code)

// Verify the user input
let userKey = "" // you got this from your DB
let result = getHotp key
if result = userInput then
  // do your thing (login successful maybe?)

Next steps

• Add QR code generator
• Make it a nuget package
• Add project configuration
• Add appveyor github actions 😁
• Add sample
• Tests?

This is just me trying stuff out, don't use in production.
