# Required features in the HSM

> Lists required HSM features needed for integration with Vectera Plus; no procedural steps, just feature requirements.

To establish a connection between the Futurex PKCS #11 library and the Excrypt HSM, you must configure the HSM with the following features:

* **PKCS 11** > Enabled.
* **Command Primary Mode** > General Purpose (GP).

To check the features with FXCLI, run `feature list` and confirm that `PKCS11` and `GPMODE` are set to `1`.

<Note>
  For additional information about how to update features on your HSM, refer to the Download Feature Request File section of the Excrypt HSM Administrator guide for your version.

<Note>
  Setting the Command Primary Mode on the HSM to General Purpose (GP) enables the option to create the FTK major key on the HSM. To use the Futurex PKCS #11 library to communicate with the HSM, you need this key. For detailed information about how to load major keys on the HSM, refer to the Excrypt HSM Administrator guide for your version.
