Upgrade Path: For HyTrust KeyControl, upgrade to 5.0 is allowed from release 4.3.2 only. For the HyTrust DataControl Policy Agent, upgrade to 5.0 is allowed from release 4.3 and higher. For details, see KeyControl Upgrades.

Changes in this release:

Version 5.0 is the first release of KeyControl on CentOS. The transition to CentOS from FreeBSD allows HyTrust to improve the security of the KeyControl operating system and to add features which were not available in FreeBSD.

The main KeyControl components were ported directly to CentOS and will continue to work as they did in earlier releases. The same is true for the KeyControl APIs. While some new commands were added, the old commands will continue to work. For a list of behavior changes in version 5.0, see What's New. All changes are described in the online help and the HyTrust DataControl Administration Guide.

Some of the major changes made in version 5.0 include:

  • Added support for encrypting Windows GPT boot drives, including those drives that use UEFI Secure Boot.
  • All data encryption now uses AES-XTS-512 encryption by default, including Linux system device encryption.
  • NTP servers are now standardized across nodes when you join a new node to an existing cluster.
  • The HyTrust support accounts have been redesigned and standardized with CloudControl. This includes an account that can be used in conjunction with HyTrust Support to reset the administrative password on a KeyControl node in case of emergencies.
  • NFS backup is now disabled by default, so the NFS ports are no longer required. You can enable NFS backup access from the KeyControl webGUI at any time.
  • KMIP servers can now require that all registered clients use TLS 1.2.
  • You can now specify the SNMP Agent port for your SNMP polling agents.
  • Decrypting a Windows boot drive now preserves thin provisioning where applicable.
  • A KeyControl Security Admin can now disable two-factor authentication (2FA) for any KeyControl-managed user account. (But only the logged in user can enable 2FA for their own account.)
  • The System Console for KeyControl nodes has been re-organized and streamlined.

Upgrade Path: For HyTrust KeyControl, upgrade to 4.1 is allowed from release 4.0 only. For the HyTrust DataControl Policy Agent, upgrade to 4.1 is allowed from release 3.3 and higher. For details, see KeyControl Upgrades.

Changes in this release:

  • Data encryption is now supported on Windows 2012 and 2016 Core Servers, as well as on VMware Cloud on AWS.
  • KeyControl now allows you to import an SSL certificate signed by the external certificate authority of your choice. This externally-signed SSL certificate replaces the default self-signed SSL certificate.

  • In release 4.0, KeyControl added the ability to specify a user-defined Key Encryption Key (KEK) for a Cloud VM Set. The KEK provides an extra layer of security by encrypting the individual data encryption keys on the VMs associated with that Cloud VM Set. Both the KEK and the individual data encryption key must be available before the information on the VM can be accessed.

    In release 4.1, KeyControl improves the security of the KEK by requiring that it be stored on an external hardware security module (HSM) associated with the KeyControl cluster. In addition, it now allows you to import a KEK into a Cloud VM Set after that Cloud VM Set has been created.

  • You can now resize an encrypted Windows data disk dynamically with no downtime.
  • You can now upload a PKS certificate when configuring an LDAP server.

Upgrade Path: For HyTrust KeyControl, upgrade to 4.0 is allowed from release 3.4 only. For the HyTrust DataControl Policy Agent, upgrade to 4.0 is allowed from release 3.2.1 and higher.

  • Support for VMtools, in particular the management tools and support for the vmxnet2 adapter.
  • Support for multi-node KPS clusters. We have tested 2 nodes but the actual number of nodes is not limited.
  • Support for external log servers via syslog.
