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. Ruby

require 'chilkat'

success = false

# 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.
numDigits = 6
# 30 second time period.
timePeriod = 30
print "Your token is: " + crypt.totp(sbKey.getAsString(),"base32","0","",timePeriod,numDigits,-1,"sha1") + "\n";
