* The Linux installer for Luna HSM Client software is compiled as .rpm packages. To install on a Debian-based distribution, such as Ubuntu, alien is used to convert the packages. We used build-essential:

apt-get install build-essential alien

If you are using a Docker container or another such microservice to install the Luna Minimal Client on Ubuntu, and your initial client installation was on another supported Linux distribution as listed above, you do not require alien. Refer to the product documentation for instructions. You might need to account for your particular system and any pre-existing dependencies for your other applications.

RHEL and CentOS 8.0-8.4 with their original kernels. See also Red Hat Enterprise Linux 8 in FIPS Mode Requires Minimal Luna HSM Client.

Advisory Notes

This section highlights important issues you should be aware of before deploying Luna HSM Client 10.4.0.

Backup/USB/PCIe Drivers Not Installed on Windows 10 or Windows Server 2022 Unless Device is Connected

Due to changes in Windows 10 and Server 2022, device drivers are not installed unless the USB or PCIe device is connected to the client workstation. If you plan to use a Luna Backup HSM 7, Luna Backup HSM G5, Luna USB HSM 7, or Luna PCIe HSM 7 with these operating systems, use one of the following workarounds:

>Connect the Luna device to the workstation (or install the Luna PCIe HSM 7 card) before installing the Luna HSM Client software

>After installing the Luna HSM Client software:

a.Connect the Luna device(s) to the workstation (or install the Luna PCIe HSM 7 card)

b.Run LunaHSMClient.exe.

c.Select the devices you want to install drivers for.

d.Click Modify.

Red Hat Enterprise Linux 8 in FIPS Mode Requires Minimal Luna HSM Client

RHEL 8.x introduced system-wide cryptographic modes. The full Luna HSM Client installer is supported only when RHEL 8.x is in DEFAULT mode. If your RHEL 8.x OS is in FIPS mode, use the minimal Luna HSM Client.

One-Step NTLS Fails on SUSE 11 Linux

Incompatibility of new Luna HSM Client components with older ones on SUSE 11 cause the one-step NTLS procedure to fail. Instead, use the multi-step procedure to establish an NTLS connection manually.

Refer to Multi-Step NTLS Connection Procedure.

Luna HSM Client No Longer Supports Luna PCIe HSM 6 on Windows

Luna HSM Client 10.4.0 and newer cannot be used with an installed Luna PCIe HSM 6.

Support for Windows Server 2012 R2 is Ended

Luna HSM Client 10.3.0 is the last version that will support Windows Server 2012 R2.

Red Hat Enterprise Linux / CentOS 6 Support is Ended

Luna HSM Client 10.2.0 is the last version that will support RHEL 6 and related operating systems. If you plan to install future client updates, consider updating your clients to RHEL 7 or 8.

Support for 32-bit OS Platforms is Ended

Starting with Luna HSM Client 10.2.0, 32-bit libraries are no longer provided. If you have a 32-bit application or integration, remain with a previous client release (such as 7.2, 7.3, or 7.4), or migrate to 64-bit platform.

Older JAVA Versions Require Patch/Update

The .jar files included with Luna HSM Client 10.x have been updated with a new certificate, signed by the Oracle JCE root certificate. This certificate validation requires a minimum Oracle JDK/JRE version.

>If your application relies on Oracle Java 7 or 8, you must update to the advanced version provided by Oracle. You require (at minimum) version 7u131 or 8u121. Please refer to Oracle's website for more information:

>If your application relies on IBM Java 7 or 8, you must install a patch from IBM before updating to Luna HSM Client 10.x (see APAR IJ25459 for details).

CKR_MECHANISM_INVALID Messages in Mixed Luna Cloud HSM Implementations

When using a Luna Cloud HSM service with Luna HSM Client, you might encounter errors like "CKR_MECHANISM_INVALID" or "Error NCryptFinalizeKey" during some operations in Hybrid HA and FIPS mode (3DES Issue). This can occur if firmware versions differ between a Luna HSM partition and a Luna Cloud HSM service in an HA group when you invoke a mechanism that is supported on one but not the other. Similarly, if one member is in FIPS mode, while the other is not, a mechanism might be requested that is allowed for one member, but not the other. For example, the ms2luna tool can fail when 3DES operations are invoked.

Resolved Issue LUNA-7585: Java DERIVE and EXTRACT flag settings for keys injected into the HSM

Formerly, the DERIVE and EXTRACT flags were forced to "true" in the JNI, which overrode any values passed by applications via Java. This was resolved in Luna HSM Client 7.3.0.

As of Luna HSM Client 7.3.0:

>The default values for the DERIVE and EXTRACT flags are set to "false" (were set to “true” in previous releases).

>JNI accepts and preserves values set by applications via the following Java calls:

LunaSlotManager.getInstance().setSecretKeysDerivable( true ); 
LunaSlotManager.getInstance().setPrivateKeysDerivable( true );
LunaSlotManager.getInstance().setSecretKeysExtractable( true );
LunaSlotManager.getInstance().setPrivateKeysExtractable( true );

NOTE   If you have existing code that relies on the DERIVE and EXTRACT flags being automatically defined by the JNI for new keys, you will need to modify your application code to set the flag values correctly.

In cases where a derived key must be extractable, add the following line to the file:
