Configuring Slot 1 with the HOTP Algorithm

To configure the HOTP-based OTP configuration on Slot 1, follow the steps below. (Slot 1 can only be configured with HOTP, while Slots 2 and 3 can be configured with either an HOTP or TOTP algorithm.)

  1. From the Applications screen, locate the OTP section and click the Slot 1 link:

  1. From the Slot 1 screen, locate the Configure section and click the Continue button:

  1. Enter your PSKC transport key:

    Note: You are only asked to enter a transport key the first time a slot is configured. This transport key is then used to encrypt all the OATH slots of a device. If you want to use another transport key for a different device, you must exit the software and run it again.

  2. On the Slot 1 Configure screen, enter the following configuration information as illustrated:

    1. Friendly Name: a human-readable name for the configured slot

    2. Algorithm: the encryption algorithm used to generate the Secret Key. The following values are available from the pull-down menu:
      1. SHA-1
      2. SHA-256
      3. SHA-512
    3. Encoding: the encoding format used to generate the Secret Key. The following values are available from the pull-down menu:
      1. Base32
      2. Base64
      3. HEX
    4. Digits: the number of OTP digits desired for the OTP display. The following values are available from the pull-down menu:
      1. 6
      2. 8
      3. 10

  3. In the example below, the following values are configured. Once entered, click the Generate button to generate the Secret Key:

    1. Friendly Name: Test OTP Configuration

    2. Algorithm: SHA-256

    3. Encoding: Base64

    4. Digits: 8

    Note: Both Numeric and Alphanumeric PINs are supported.

  4. When the configuration completes, a success message appears in the upper-right corner of the Crescendo Management Tool window:
