Decrypt the output from the yubikey token The hardware can be found at http://www.yubico.com/home/index/ The decryption module does only one thing - decrypt the AES encrypted OTP from the Yubikey. To this, it requires the OTP, and the AES key. Please note - this module does not perform authentication - it is a required component to decrypt the token first before authentication can be performed.
