  2. Bootstrap Client SDK 5. For more information about bootstrapping, see Bootstrap the Client SDK.

  3. Locate the following JCE provider files:

    Linux

    • /opt/cloudhsm/java/cloudhsm-version.jar

    • /opt/cloudhsm/bin/configure-jce

    • /opt/cloudhsm/bin/jce-info

    Windows

    • C:\Program Files\Amazon\CloudHSM\java\cloudhsm-version.jar>

    • C:\Program Files\Amazon\CloudHSM\bin\configure-jce.exe

    • C:\Program Files\Amazon\CloudHSM\bin\jce_info.exe

Provide credentials to the JCE provider

Before your Java application can use an HSM, the HSM needs to first authenticate the application. HSMs authenticate using either an explicit login or implicit login method.

Explicit login – This method lets you provide AWS CloudHSM credentials directly in the application. It uses the method from the AuthProvider, where you pass a CU username and password in the pin pattern. For more information, see Login to an HSM code example.

Implicit login – This method lets you set AWS CloudHSM credentials either in a new property file, system properties, or as environment variables.

  • System properties – Set credentials through system properties when running your application. The following examples show two different ways that you can do this:

    Linux
    $ java -DHSM_USER=<HSM user name> -DHSM_PASSWORD=<password>
    System.setProperty("HSM_USER","<HSM user name>");
System.setProperty("HSM_PASSWORD","<password>");
    Windows
    PS C:\> java -DHSM_USER=<HSM user name> -DHSM_PASSWORD=<password>
    System.setProperty("HSM_USER","<HSM user name>");
System.setProperty("HSM_PASSWORD","<password>");

  • Environment variables – Set credentials as environment variables.

    Linux
    $ export HSM_USER=<HSM user name>
$ export HSM_PASSWORD=<password>
    Windows
    PS C:\> $Env:HSM_USER="<HSM user name>"
PS C:\> $Env:HSM_PASSWORD="<password>"

Credentials might not be available if the application does not provide them or if you attempt an operation before the HSM authenticates session. In those cases, the CloudHSM software library for Java searches for the credentials in the following order:

  1. System properties

  2. Environment variables

Key management basics in the JCE provider

The basics on key management in the JCE provider involve importing keys, exporting keys, loading keys by handle, or deleting keys. For more information on managing keys, see the Manage keys code example.

You can also find more JCE provider code examples at Code samples.
