Generates a 6-digit time-based TOTP code using a base32 secret with a 30-second time period. Xojo Plugin

Dim success As Boolean
success = False

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// 
Dim crypt As New Chilkat.Crypt2

// Base32 secret key:
Dim secretKey As String
secretKey = "oebf ytfl qmzb p4xd 2ztf zyz4 hjrw 3uyo"

Dim sbKey As New Chilkat.StringBuilder
success = sbKey.Append(secretKey)

// Remove SPACE chars.
Dim numRemoved As Int32
numRemoved = sbKey.Replace(" ","")

// Note: A new token is generated every 30 seconds.  You must generate within the same 30 second interval to get the same result.

// Generate 6 digits.
Dim numDigits As Int32

// 30 second time period.
Dim timePeriod As Int32
