SignServer Hardware Appliance 5.1.2 Release Notes

AUGUST 2025

We are pleased to announce the release of SignServer Hardware Appliance 5.1.2.

With this release, we have added support for FIPS enablement with both variants of HSMs: Luna S790 and u.trust and Se100/Se2K.

The release also brings a list of improvements and bug fixes.

Highlights

Version of SignServer Enterprise

This release is delivered with SignServer 7.3.2. For more information, see the SignServer Release Notes.

New Features

• Using the HSM in FIPS mode: with this release it is possible to select during the first installation or when restoring a backup either to run the HSM in FIPS mode or not. The procedure to enable FIPS mode might require extra steps compared to the non-FIPS setup of the HSM. Please refer to the documentation for further details.

Improvements and Corrections

The following lists other corrections included in the release.

• Bug fixes:

  • Backup tab crashes on webconf when trying to connect to non reachable NFS server.

  • Factory reset not successful without a configured DHCP or Static IP address

  • If a backup taken from version 5.1.1 or older and restored on one of the mentioned version, the u.trust HSM Firmware update process will be broken.

Upgrade Information

• If a u.trust firmware update is not successful on version 5.1.0 or 5.1.1 on an appliance that has been restored from a backup that was taken on version 5.1.1 or older, you need take a new backup, factory reset the appliance, update the appliance to version 5.1.2 then restore the taken backup.

Downgrade Information

• Downgrading of the firmware version of the appliance would also require downgrading the u.trust HSM firmware version if the versions between these two firmware versions are different.
  A factory reset of the appliance would therefore be mandatory.
