Adding a TSIG key - BlueCat Address Manager - 9.2.0

Address Manager Administration Guide

BlueCat Address Manager

To create a TSIG key, you specify a name for the key, an algorithm, and the length of the key in bits.

Address Manager can create the key value automatically, or you can manually type a Base64-encoded string for the key. Use the manual option when you need to add keys that already exist on your DNS and DHCP servers to Address Manager.

To add a TSIG key:

  1. From the configuration drop-down menu, select a configuration.
  2. Select one of the following tabs: IP Space, DNS, Devices, TFTP, or Servers. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  3. Click the TSIG Keys tab.
  4. Under TSIG Keys, click New.
  5. Under General, set the key name, algorithm, and length:
    • Name—enter a name for the TSIG key. The name can't contain spaces.
    • Algorithm—select an algorithm for the key, either hmac-md5, hmac-sha1, hmac-sha256. or hmac-sha512.
      • Forward and Reverse DHCP Zones only support hmac-md5 keys. If you want to secure Forward or Reverse DHCP Zones, you must create one or more TSIG keys with the hmac-md5 algorithm.
      • TSIG keys that use the hmac-sha512 are only supported on DNS/DHCP Server v9.0.0 and greater.
    • Length (bits)—select the length of the key, either 128, 256, or 512 bits.
  6. Under Key Type, select an option for generating the key value:
    • Auto-generate—select this option to generate the key automatically. Keys created with this option can be regenerated with the Emergency Rollover function.
    • Enter manually—select this option to type or copy and paste the key manually in the Secret field. Keys created with this option can't be regenerated with the Emergency Rollover function.
    • Secret—this field is available for use when you select Enter manually. Enter or copy and paste a Base64-encoded key string in this field. The key must match the algorithm and length options selected in the Algorithm and Length (bits) fields.
  7. Under Change Control, add comments, if required.
  8. Click Add.
