The Futurex CNG library uses the fxcng.cfg configuration file to connect to the HSM. It enables you to modify certain configurations and set connection details. This section covers the <HSM> portion of the FXCNG config file, where you set the connection details.
By default, the FXCNG library looks for the configuration file at C:\Program Files\Futurex\fxcng\fxcng.cfg. Alternatively, you can set the FXCNG_CFG environment variable to the location of the fxcng.cfg file.
Open the fxcng.cfg file in a text editor as an administrator and edit it accordingly.

FieldDescription
<SLOT>Leave it set to the default value of 0.
<LABEL>Leave it set to the default value of Futurex.
<CRYPTO-OPR>Specify the name of the identity created for the application partition.
<CRYPTO-OPR-PASS>Specify the password of the identity configured in the <CRYPTO-OPR> field. Use this to log the application into the HSM automatically if required.
<ADDRESS>Specify the IP address of the HSM to which the FXCNG library should connect.
<PROD-PORT>Set the port number of the HSM that the FXCNG library should connect to.
<PROD-TLS-ENABLED>Set the field to YES.
<PROD-TLS-ANONYMOUS>Defines whether the FXPKCS11 library authenticates to the server.
<PROD-TLS-ENGINE>Setting the define to WINDOWS specifies that the TLS connection certificate is saved in the Windows Certificate Store rather than the local file system.
<PROD-TLS-WIN-STORE>Specifying My in this field tells the FXCNG library to look for the TLS client certificate in the Personal Windows Certificate Store.
<PROD-TLS-KEY>Specifies the Common Name of the TLS client certificate.
<PROD-TLS-CA>You can use multiple instances of this define to specify where to save the CA certificate(s) in the file system. FXCNG does not pull CAs from the Windows Certificate Store.
<FX-LOAD-BALANCE>Set this field to YES if you use a Guardian to manage HSM devices in a cluster.
If you don’t use a Guardian, set it to NO
After you finish editing the fxcng.cfg file, run the CNGInstallUtil file to test the connection against the HSM, and check the FxCNG-Install-Log.txt file for errors and information.
