;  To duplicate the results of the Authenticator Test at https://rootprojects.org/authenticator/
;  do the following:
;  1) At the bottom of the screen you will see a URI such as:
;  
;     otpauth://totp/ACME%20Co:john@example.com?secret=HXDMVJECJJWSRB3HWIZR4IFUGFTMXBOZ&issuer=ACME%20Co&algorithm=SHA1&digits=6&period=30
;  
;     Use the uppercase secret.  For example:
Local $secretKey = "HXDMVJECJJWSRB3HWIZR4IFUGFTMXBOZ"

;  2) DO NOT cick the "Regenerate" button.  The regenerate button will generate a new secret.
;  
;  3) Run the following code to generate your 6-digit token.  Compare with the token shown in the picture of the iPhone at https://rootprojects.org/authenticator/
;       Note: A new token is generated every 30 seconds.  You must generate within the same 30 second interval to get the same result.
ConsoleWrite("Your token is: " & $oCrypt.Totp($secretKey,"base32","0","",30,6,-1,"sha1") & @CRLF)

;  ---------------------------------------------------------------------------------------------
;  To duplicate the results of the Google2FA Playground at https://pragmarx.com/playground/google2fa#/
;  do the following:

;  1) Copy the 64-byte secret key:
$secretKey = "OR2VQTRVHB2HO2LCGVWXQSCDK5ZHQS2D3THQ6UXO57XIE7ZHOWS6HDPQ622GU747"

;  2) Run the same code:
;     (Note: The online tool generates a new result every 30 seconds.  You must generate and compare within the same 30-second interval.)
ConsoleWrite("Your token is: " & $oCrypt.Totp($secretKey,"base32","0","",30,6,-1,"sha1") & @CRLF)
