NTP Key Type SHA Values

As of LoadMaster firmware version 7.2.52 (and LTS version, the SHA-1 hashing algorithm has been added to the key types supported for NTP on the System Configuration > System Administration > Date/Time User Interface (UI) page. Select the Show NTP Authentication Parameters check box to display the NTP Key Type drop-down list. In previous releases, SHA-1 was presented as a choice; however, this was actually implementing the legacy SHA (that is, SHA-0) hashing algorithm. This has been corrected in this release, so that the three key types supported are now: MD5, SHA-1, and legacy SHA. MD5 remains the default.

Application Programming Interface (API) Details

You can retrieve the value of the ntpkeytype parameter using the RESTful API get command, for example:


You can configure the value of the ntpkeytype parameter using the set command, for example:


Valid values for the ntpkeytype parameter are:

  • M (MD5)
  • SHA1 (SHA-1)
  • SHA (legacy SHA)

These values are case sensitive.

For further details on the RESTful API in general, refer to the RESTful API Interface Description document.
