Entrust HSM Encryption

Protect Secrets Manager connection details locally with Entrust HSM

Keeper Secrets Manager integrates with Entrust HSM in order to provide encryption for Keeper Secrets Manager configuration files. With this integration, you can protect connection details on your machine while taking advantage of Keeper's zero-knowledge encryption of all you secret credentials.

Features

• Encrypt and Decrypt your KSM configuration files with Entrust HSM

• Protect against unauthorized access to your Secrets Manager connections

• Requires only minor change to code for immediate protection. Works with all KSM Python SDK functionality

Prerequisites

• Supports the Python Secrets Manager SDK

• The Python module needs to be built as a nShield native application

  • Using Python (v3.8.5) and nfpython modules from SDK ISO image from Entrust nShield software (Security World 12.80 or later)

• Virtualenv is recommended

Setup

1. Create and Configure Virtualenv

This step is optional, but recommended for development

Linux

Create a virtualenv environment to work in

/opt/nfast/python3/bin/python3 -m venv --copies venv

Activate the virtualenv environment before starting development

. venv/bin/activate

Windows

2. Install KSM Storage and nfpython Modules

The Secrets Manager HSM modules are located in the Keeper Secrets Manager storage module which can be installed using pip

pip3 install keeper-secrets-manager-storage

The nfpython package also needs to be installed in order to utilize the Entrust HSM. This package is installed as part of the nShield package with your Entrust installation.

In Linux:

pip install /opt/nfast/python3/additional-packages/nfpython*.whl 

In Windows:

pip install c:\Program Files\nCipher\nfast\python3\additional-packages\nfpython*.whl

3. Add Entrust HSM Storage to Your Code

Use the HsmNfastKeyValueStorage as your Secrets Manager storage in the SecretsManager constructor.

The HsmNfastKeyValueStorage requires the method and identity ("simple" and "ksmkey" respectively in this example).

entrust_hsm_example.py

from keeper_secrets_manager_core import SecretsManager
from keeper_secrets_manager_hsm.storage_hsm_nfast import HsmNfastKeyValueStorage

config=HsmNfastKeyValueStorage('simple', 'ksmkey', 'client-config.json')

secrets_manager = SecretsManager(config=config, verify_ssl_certs=True)

all_records = secrets_manager.get_secrets()

You're all set and ready to use Secrets Manager with Entrust NShield HSM

Using Secrets Manager with Entrust HSM

Once setup, the Secrets Manager Entrust integration supports all Secrets Manager SDK functionality. Your code will need to be able to access the nShield HSM in order to manage the decryption of the configuration file when run.

Check out the KSM SDKs documentation for more examples and functionality

Create an Encryption Key for Testing

In order to test encryption with the Entrust nShield HSM, use the following command:

Replace "ksmkey" in these examples with the identity in your HSM.

in Linux:

opt/nfast/bin/generatekey -b simple protect=module type=AES size=256 ident=ksmkey

in Windows:

c:\Program Files\nShield\nfast\bin\generatekey -b simple protect=module type=AES size=256 ident=ksmkey
