Multiple CNG/KSP Provider Instances

CNG/KSP Provider V1.40 onwards allows installing multiple CNG/KSP provider instances. These can only be installed using procedures based on the KspCfg.ini configuration file and the number of provider instances can only be changed via the installation procedure.

Installation of Multiple Provider Instances​

Adapt the KspCfg.ini sample file, located within the setup folder. The section PROVIDERS of the KspCfg.ini configuration file defines how many provider instances will be installed including their naming:

[PROVIDERS]

PROVIDER_1 = Securosys Primus HSM Key Storage Provider 1

PROVIDER_2 = Securosys Primus HSM Key Storage Provider 2

PROVIDER_3 = Securosys Primus HSM MyPartition

PROVIDER_4 = Customer ABC

Delete further sections in case you configure the provider instances via the graphical Securosys "Key Storage Provider Configuration" tool.

To configure the provider during the installation procedure (e.g. Active Directory), define the other sections with the necessary configuration parameters per provider instance. See KspCfg.ini sample file for explanations.

The following example shows the configuration for a provider using a developer account and a second provider using a Clouds HSM Sandbox partition:

[PROVIDERS]

PROVIDER_1 = Primus Dev MY-PARTITION

PROVIDER_2 = Primus Sandbox TEST-PARTITION

[PROVIDER_1.HSM_1]

ID = Grimsel_MY-Partition

HOSTNAME = grimsel.securosys.ch

PORTNUMBER = 2320

PRIORITY = 0

HSM_USERNAME = MY-PARTITION

HSM_PASSWORD = KC5b2-VX5NZ-…-8CbGZ-1NCre

[PROVIDER_2.HSM_1]

ID = CloudHSM-Sandbox_TEST-PARTITION

HOSTNAME = a-api.cloudshsm.com

PORTNUMBER = 2320

PRIORITY = 0

HSM_USERNAME = TEST-PARTITION

HSM_PASSWORD = KC5b2-VX5NZ-…-8CbGZ-1NCre

PROXY_USERNAME = myServiceUserName

PROXY_PASSWORD = ivd0rra…s4mpgb7

[PROVIDER_2.HSM_2]

ID = CloudHSM-Sandbox_TEST-PARTITION

HOSTNAME = b-api.cloudshsm.com

PORTNUMBER = 2320

PRIORITY = 0

HSM_USERNAME = TEST-PARTITION

HSM_PASSWORD = KC5b2-VX5NZ-…-8CbGZ-1NCre

PROXY_USERNAME = myServiceUserName

PROXY_PASSWORD = ivd0rra…s4mpgb7

Increase the Number of Installed Provider Instances​

The number of provider instances can only be changed by reinstalling the providers. We suggest the following procedure (requiring administrator rights, but no new setup password):

  • First update to CNG/KSP Provider V1.41+, the regular way (if an older version is installed)
  • Open a CMD shell with administrator rights and export the current configuration with the following command (contains blinded secrets!):
"%ProgramFiles%\Securosys\PrimusHsmKsp\kspcfgcons.exe" ExportCfg OldConfig.ini
  • Copy this configuration file OldConfig.ini to KspCfg.ini within your setup folder
  • Adapt the configuration, section PROVIDERS by adding the providers according to your needs (quantity and provider naming). Add the new configuration parameters as shown in Installation of Multiple Provider Instances or configure them later via the GUI.

Example:

[PROVIDERS]

PROVIDER_1 = Securosys Primus HSM Key Storage Provider

PROVIDER_2 = Securosys Primus HSM New Partition

[PROVIDER_1.HSM_1]

ID = Grimsel Internal

DEVICENAME = GRIMSEL

HOSTNAME = grimsel.securosys.ch

PORTNUMBER = 2320

PRIORITY = 0

…
  • Uninstall the current CNG/KSP Provider
  • Install the CNG/KSP Provider again by applying the following command, using the configuration file KspCfg.ini located within your setup folder :
MsiExec /quiet /i setup_x64.msi INSTALLCFG=1

Please note, that any errors in the KspCfg.ini file will fail to install the providers!
