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

crypt = Chilkat::CkCrypt2.new()

# Base32 secret key:
secretKey = "oebf ytfl qmzb p4xd 2ztf zyz4 hjrw 3uyo"

sbKey = Chilkat::CkStringBuilder.new()
success = sbKey.Append(secretKey)

# Remove SPACE chars.
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.
