Generate TOTP using Base32 Secret (6 Digits, Time-based, 30-second period)

See more Encryption Examples

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

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")

Set outFile = fso.CreateTextFile("output.txt", True, True)

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Remove SPACE chars.

' 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.
